Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean remote sensing, and in particular to a sea wave data registration method and system, a computer readable storage medium and an electronic device. BACKGROUND

[0002] For sea wave observation, data sources can be roughly divided into two categories, remote sensing observation and field observation. Field observation means represented by buoys can provide high-quality and accurate sea wave parameters, but the spatial coverage of such fixed-position field observation is very limited; in contrast, remote sensing observation means represented by altimeters, synthetic aperture radars and sea wave spectrometers, although the accuracy is relatively low compared to field observation, can provide almost global coverage of sea wave observation data, and is another important data source for sea wave observation.

[0003] During the operation of a sea wave remote sensor on a satellite, the data of remote sensing observation and field observation need to be registered, that is, the remote sensing and field observation at the same observation time and the same observation position are registered. The revisit time of a sea wave remote sensor is very long, and is subject to orbital constraints. Therefore, the spatio-temporal position of remote sensing observation cannot be completely consistent with field buoy observation means, making it difficult to perform efficient registration. SUMMARY

[0041] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the protection scope of the present application.

[0042] The field observation sea wave data is the sea wave data monitored by the buoy set on the sea surface.

[0043] The remote sensing observation sea wave data is the sea wave data monitored by the sea wave remote sensor (such as altimeter, synthetic aperture radar and sea wave spectrometer) on the satellite.

[0044] Model-reported wave data, also known as model-reported wave parameter data, can be obtained by selecting global wave reanalysis data (e.g., ERA5 wave data), publicly available wave-reported datasets (e.g., the IOWAGA dataset), or by using reanalysis wind fields (e.g., ERA5, CFSR, etc.) and wave boundary conditions within the specified time frame to drive global (without wave boundary conditions) or regional (with wave boundary conditions) numerical wave models (e.g., WAVEWATCH III, SWAN, etc.) to obtain wave model output. The temporal resolution of global and regional wave model outputs should be no less than 3 hours, and the spatial resolution should be no less than 0.5°. The parameterization scheme used needs to consider the effects of wind input, dissipation, and four-wave interactions. The output parameters include wave spectrum integral parameters such as significant wave height, mean period, and mean direction. If the remote sensing wave data and field observation wave data to be registered are located in nearshore shallow waters, the model-reported wave data should use the aforementioned low-resolution wave reports as boundary conditions, employing relatively refined water depth and shoreline information, and utilizing the reanalysis wind field of the target area to drive the numerical wave model. The temporal resolution of the wave model output should be no less than 3 hours, and the highest spatial resolution should be no less than 10 km. The digitization scheme used must consider not only input, dissipation, and four-wave interaction, but also the effects of depth-induced breaking dissipation and bottom friction.

[0045] Ocean wave data, also known as ocean wave parameters or wave parameters, includes significant wave height, average period, average direction, spectral peak frequency, and spectral peak direction.

[0046] The remote sensing wave data, model-reported wave data, and on-site observed wave data in this embodiment are all past wave data, not real-time wave data.

[0047] In this embodiment, the wave data used is significant wave height data.

[0048] Figure 1 This is a flowchart illustrating the wave data registration method provided in an embodiment of the present invention. Figure 1 As shown, the wave data registration method of this invention, after finding a registration pattern with remotely sensed wave data, reports the wave data; specifically, it includes the following steps:

[0049] S101: After acquiring the remote sensing observation wave data and pattern of the first location, report the wave data.

[0050] Given the spatiotemporal location of a remotely sensed ocean wave data point at a first location. The time and longitude and latitude information, and the corresponding significant wave height data; for example, the remote sensing observation data of the significant wave height of a observation point in the sea area around the United States. The significant wave height data of the mode post-analysis wave data corresponding to the first position is obtained in the ERA5 sea wave post-analysis reanalysis (the numerical wave mode post-analysis data of the ERA5 reanalysis is used in this embodiment), and the data time resolution is 3 hours, and the spatial resolution is 0.5 degrees.

[0051] S102: Obtain the live observation wave data and the mode post-analysis wave data of a plurality of second positions without land between the first position within a preset time.

[0052] The preset time is determined as the first time threshold to the second time threshold at the time of the first position.

[0053] Specifically, the first time threshold and the second time threshold are both 1 hour, and the preset time is within one hour before and after the time at which the remote sensing observation wave data (i.e. the remote sensing significant wave height data) of the first position is obtained. For example, according to the observation time of the to-be-registered remote sensing significant wave height data, a plurality of buoy live observation significant wave height data of the National Data Buoy Center of the United States without land between the observation position within the time range is selected (the live observation data used in this embodiment is the live observation data of the National Data Buoy Center of the United States). At the same time, the ERA5 sea wave post-analysis reanalysis significant wave height data (i.e. the significant wave height data of the mode post-analysis wave data, the numerical wave mode post-analysis data of the ERA5 reanalysis is used in this embodiment) in the period is collected, the data time resolution is 3 hours, and the spatial resolution is 0.5 degrees.

[0054] S103: Determine the denoised live observation wave data based on the live observation wave data and the mode post-analysis wave data of the same second position.

[0055] Specifically, S1031: Determine the difference between the live observation wave data and the mode post-analysis wave data of the same second position;

[0056] S1032: Determine the sliding average difference based on the difference;

[0057] S1033: Superimpose the sliding average difference and the mode post-analysis wave data of the second position to obtain the denoised live observation wave data.

[0058] Taking one of the plurality of second positions, the second position corresponds to the i-th buoy, i.e. taking the position of the i-th buoy in the plurality of buoys, the significant wave height of the live observation wave data O i,ori of the i-th buoy is taken, and the mode post-analysis wave data F iThe significant wave heights are subtracted, and this difference is then averaged over 5 points (or 3 points) to obtain the averaged difference (i.e., the moving average difference). This averaged difference is then superimposed onto the pattern at that location and reported as wave data F. i At the wave height, denoised on-site observation wave data O was obtained. i Effective wave height.

[0059] The specific calculation is performed using the following formula:

[0060] O i =F i +runningAVG(O i,ori -F i ).

[0061] S104: Based on multiple sets of denoised field observations and post-mode wave data from the second location, correct the post-mode wave data from the first location and determine the corrected post-mode wave data from the first location.

[0062] In this embodiment, based on the residuals of the effective wave height data of the denoised on-site observation wave data at multiple second locations and the effective wave height data of the pattern-reported wave data, the pattern-reported wave data at the first location is corrected by the rules of residual spatial interpolation to obtain the corrected pattern-reported wave effective wave height data at the first location.

[0063] The rules for residual space interpolation are as follows:

[0064]

[0065]

[0066]

[0067] Among them, F b The wave data is reported after the first position pattern, F. Cref The wave data is reported after the correction mode for the first position, N. ref This indicates the number of second locations that can be obtained within a preset time period, where there is no land between the first location and the second location. i F represents the denoised on-site observation of ocean waves at the i-th second position. i This indicates that wave data is reported after the i-th second position pattern; w i It is the weighting coefficient of the i-th second-position field observation location; It is the i-th second position to the first position If there is land along the great circle connecting the i-th second position to the first position, then this distance of latitude and longitude will... Treat it as positive infinity and set a very large value (e.g., 999999km); That is The distance from this first position to its nearest second position that does not cross land; in the formula, m and n are the distance scaling factor and the shortest distance amplification factor in the difference process, respectively, usually taken as m=2 and n=0. However, it can also be derived from N at each time step. ref N were extracted from the observations. test Given a set of data, with different values ​​of m and n, only N is used. ref -N test Pattern correction is performed using N data points, and the remaining N data points are used for further correction. test The data are used to evaluate the correction effect, and the values ​​of m and n with the best correction effect are selected. S105: When the distance between the first position and the nearest second position is less than the preset distance D, and the deviation between the pattern-reported wave data of the first position and the pattern-reported wave data of the nearest second position is less than the deviation threshold G, the corrected pattern-reported wave data of the first position is determined as the registration data of the wave remote sensing observation data of the first position.

[0068] The root mean square error between the significant wave height of remote sensing wave observation data and on-site wave observation data obtained using traditional registration methods is about 0.3 meters. After testing, when D is 300 km, the root mean square error of remote sensing wave observation data and on-site wave observation data obtained using the method proposed in this invention also reaches 0.3 meters. Therefore, D = 300 km is taken as the value in this case.

[0069] G is a preset deviation threshold, which in this embodiment refers to the deviation threshold of the wave height data, and can be set to 0.6 meters.

[0070] For the ocean wave remote sensing observation data to be registered, perform the above steps respectively to obtain the set of all registered data that meet the conditions.

[0071] Using this invention, without increasing the root mean square error between remote sensing data and on-site wave observation data, the number of registered data pairs obtained by traditional registration methods is increased by more than 30 times. This makes it possible to perform more refined error analysis under various sea conditions and wind speeds.

[0072] Furthermore, assuming that a satellite requires 200 sets of registration data for preliminary calibration and verification of effective wave height after launch, if the traditional method takes about 3 months to complete the data accumulation, then with this method, more than 400 sets of data can be accumulated in just about a week, significantly reducing the time required for satellite data testing in the early stage and effectively improving efficiency.

[0073] Figure 2This is a schematic diagram of a wave data registration system provided in an embodiment of the present invention. The embodiment of the present invention also provides a wave data registration system, such as... Figure 2 As shown, the system includes:

[0074] The acquisition module S201 is used to acquire remote sensing observation wave data and pattern-reported wave data at the first location.

[0075] Given the spatiotemporal location of a remotely sensed ocean wave data point at a first location. This includes time and latitude / longitude information, as well as the corresponding significant wave height data (in this embodiment, significant wave height data of ocean waves is used); for example, ocean wave data from an observation point in the waters surrounding the United States. The significant wave height data of the model-reported ocean wave data corresponding to this first location is obtained in the ERA5 wave reanalysis (in this embodiment, numerical wave model reanalysis data from ERA5 is used). This data has a time resolution of 3 hours and a spatial resolution of 0.5 degrees.

[0076] The acquisition module S201 is also used to acquire on-site observed wave data and pattern-reported wave data from multiple second locations within a preset time period that are not connected to the first location and have no land between them.

[0077] The preset time here is defined as the time between the first time threshold and the second time threshold at the time of the first position.

[0078] Specifically, both the first and second time thresholds are 1 hour, with the preset time being one hour before and one hour after the time when the remote sensing observation wave data (i.e., remote sensing wave significant wave height data) at the first location is acquired. For example, based on the observation time of the remote sensing wave significant wave height data to be registered, wave significant wave height data from several buoys of the U.S. National Buoy Data Center that are not connected to the remote sensing observation location within this time range are selected (the field observation data used in this embodiment is the field observation data of the U.S. National Buoy Data Center, and the wave data used is the wave significant wave height). At the same time, wave post-analysis significant wave height data of ERA5 (i.e., the significant wave height data of model post-analysis wave data; in this embodiment, the numerical wave model post-analysis data of ERA5 is used) is collected within this time period. This data has a time resolution of 3 hours and a spatial resolution of 0.5 degrees.

[0079] The module S202 determines the denoised on-site observed wave data and pattern-reported wave data based on the same second location.

[0080] Specifically, S1031: Determine the difference between the on-site observed wave data and the wave data reported by the model at the same second location;

[0081] S1032: Determine a sliding average difference value based on the difference value;

[0082] S1033: Superimpose the sliding average difference value on the mode post-forecast sea wave data of the second position to obtain the denoised field observation sea wave data.

[0083] Take one of the plurality of second positions corresponding to the i-th buoy, i.e., take the position of the i-th buoy in the above-mentioned several buoys, and subtract the significant wave height in the field observation sea wave data O i,ori of the i-th buoy from the significant wave height in the mode post-forecast sea wave data F i of the position, and perform 5-point sliding average (or 3-point sliding average) on the difference value to obtain a sliding average difference value, and then superimpose the sliding average difference value on the wave height of the mode post-forecast sea wave data F i of the position to obtain the significant wave height of the denoised field observation sea wave data O i .

[0084] Specifically, the following formula is used for calculation:

[0085] O i = F i + runningAVG(O i,ori -F i ).

[0086] The determining module S202 is further configured to correct the sea wave mode post-forecast data of the first position based on the denoised field observation sea wave data and the mode post-forecast sea wave data of the plurality of second positions, and determine the corrected mode post-forecast sea wave data of the first position.

[0087] In this embodiment, the mode post-forecast sea wave data of the first position is corrected based on the residual error between the significant wave height data of the denoised field observation sea wave data of the plurality of second positions and the significant wave height data of the mode post-forecast sea wave data, and the corrected mode post-forecast sea wave significant wave height data of the first position is obtained through a residual error spatial interpolation rule.

[0088] The residual error spatial interpolation rule is as follows:

[0089]

[0090]

[0091]

[0092] wherein F b represents the mode post-forecast sea wave data of the first position, F Cref represents the corrected mode post-forecast sea wave data of the first position, and N refThis indicates the number of second locations that can be obtained within a preset time period, where there is no land between the first location and the second location. i F represents the denoised on-site observation of ocean waves at the i-th second position. i This indicates that wave data is reported after the i-th second position pattern; w i It is the weighting coefficient of the i-th second-position field observation location; It is the i-th second position to the first position If there is land along the great circle connecting the i-th second position to the first position, then this distance of latitude and longitude will... Treat it as positive infinity and set a very large value (e.g., 999999km); That is The distance from this first position to its nearest second position that does not cross land; in the formula, m and n are the distance scaling factor and the shortest distance amplification factor in the difference process, respectively, usually taken as m=2 and n=0. However, it can also be derived from N at each time step. ref N were extracted from the observations. test Given a set of data, with different values ​​of m and n, only N is used. ref -N test Pattern correction is performed using N data points, and the remaining N data points are used for further correction. test The data are used to evaluate the correction effect, and the values ​​of m and n with the best correction effect are selected.

[0093] The determining module S202 is further configured to determine the corrected mode-reported wave data of the first position as the registration data of the remote sensing observation data of the waves at the first position when the distance between the first position and the nearest second position is less than a preset distance D, and the deviation between the mode-reported wave data of the first position and the mode-reported wave data of the nearest second position is less than a deviation threshold G.

[0094] The root mean square error between the significant wave height of remote sensing wave observation data and on-site wave observation data obtained using traditional registration methods is about 0.3 meters. After testing, when D is 300 km, the root mean square error of remote sensing wave observation data and on-site wave observation data obtained using the method proposed in this invention also reaches 0.3 meters. Therefore, D = 300 km is taken as the value in this case.

[0095] G is a preset deviation threshold, which in this embodiment refers to the deviation threshold of the wave height data, and can be set to 0.6 meters.

[0096] For the ocean wave remote sensing observation data to be registered, perform the above steps respectively to obtain the set of all registered data that meet the conditions.

[0097] The application increases the number of registration data pairs by more than 30 times compared to the registration data pairs obtained by the traditional registration method without increasing the root mean square error between the sea wave remote sensing observation data and the sea wave field observation data, which makes it possible to perform more detailed error analysis under various sea conditions and different wind speeds.

[0098] In addition, assuming that 200 sets of registration data are needed for the effective wave height preliminary calibration and verification of a satellite after launch, if the traditional method is used, it takes about 3 months to accumulate the data, and if the method is used, more than 400 sets of data can be accumulated in about one week, which significantly reduces the time needed for the satellite in the early data test and effectively improves the efficiency.

[0099] The embodiment of the application also provides a computer readable storage medium, which stores programs or instructions, and when the programs or instructions are run on a computer, the computer executes the sea wave data registration method as described in the first embodiment.

[0100] As shown in Figure 3 The embodiment of the application also provides an electronic device 300, which comprises a processor 301 and a memory 302 coupled with the processor 301,

[0101] The processor 301 is configured to read and execute the computer program stored in the memory, so as to implement the sea wave data registration method as described in the above method embodiment.
