It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] See also Figure 1 , is a flow chart of the steps of a method for storing water vapor chromatography results in the first embodiment of the present application, which is used to store the water vapor chromatography results in a text file, the text file includes a header information storage text and a result information storage text, so as to achieve standardized storage of water vapor chromatography results, which is conducive to promoting the standardization, engineering and large-scale application of water vapor chromatography technology. The method includes:

[0028] Step 101, storing the observation information of the water vapor tomography result into the header information storage text, and displaying the observation information; wherein the observation information includes the grid division of the tomography grid in the south, north and high directions, the start time of the observation data, the end time of the observation data, the number of valid rays, the total number of grids, the source of prior information, the constraint information, the processing mode and the tomography algorithm;

[0029] Step 102, storing the water vapor chromatography results in the result information storage text according to the height layers, and displaying the chromatography results;

[0030] Step 103: store the accuracy information of the water vapor tomography result and the accuracy information of the observation values ​​involved in the tomography result in a text file after the water vapor tomography result, and display the accuracy information.

[0031] For details, please refer to Figure 2 The header information part starts with "#+comment name", and each line describes a comment content. This part mainly includes the grid division of the tomography grid in the south, north, and high directions, the start time of the observation data, the end time of the observation data, the number of valid rays, the total number of grids, the source of prior information, constraint information, processing mode, tomography algorithm, etc. The result information part mainly stores the water vapor tomography results in layers.

[0032] The present invention stores the observation information when observing the water vapor chromatography result in the header information storage text of the text file, so that the text file can clearly record the observation information of the water vapor chromatography result, stores the chromatography results of the water vapor chromatography result in layers in the result information storage text, stores the precision information of the water vapor chromatography result and the precision information of the observation value involved in the chromatography result in the text file after the water vapor chromatography result, and displays the observation information, result information and precision information. The result information storage texts of different layers can display the chromatography results of different layers, so as to display the chromatography results concisely and clearly, so as to achieve the standardized storage of the water vapor chromatography result, which is conducive to promoting the standardized, engineering and large-scale application of the water vapor chromatography technology.

[0033] In the specific embodiments, see Figure 3 , the text file also includes a first precision information storage text, then the precision information of the water vapor tomography result is stored in the text file after the water vapor tomography result, including: obtaining the covariance matrix of the water vapor tomography result, storing the covariance matrix in the first precision information storage text, and displaying the covariance matrix.

[0034] Specifically, the diagonal elements in the covariance matrix represent the variance of the tomography results in different grids in the tomography area, which are used to measure the error of the tomography results. The off-diagonal elements represent the correlation between the tomography results between different grids. The above results can be used to analyze the reliability of the results.

[0035] In the specific embodiments, see Figure 3, the text file also includes a second precision information storage text, then storing the precision information of the observation values ​​involved in the tomography results of the water vapor tomography results in the text file after the water vapor tomography results includes: obtaining the mean error vector corresponding to the observation values ​​involved in the water vapor tomography results, storing the mean error vector in the second precision information storage text, and displaying the mean error vector.

[0036] Specifically, the mean error is a numerical standard for measuring observation accuracy, also known as the "standard deviation", which is a quantitative expression of the accuracy of the observation value. The mean error provides a quantitative indicator for the accuracy of the observation value corresponding to the water vapor tomography result. By comparing the mean errors of different observations or models, their observation accuracy or model prediction ability can be intuitively evaluated. The smaller the mean error, the closer the observation or prediction result is to the true value, and the higher the accuracy. When processing water vapor tomography data, the mean error can be used as an important basis for judging data quality. For observation data with large mean errors, further inspection or elimination may be required to improve the reliability of the overall data.

[0037] In a specific embodiment, storing the water vapor chromatography results in the result information storage text in layers according to height includes: the water vapor chromatography results are represented by wet refractive index or water vapor density, and the water vapor chromatography results are stored in the result information storage text in layers from low to high. The first layer in the result information storage text is used to store the first layer horizontal tomography results of the water vapor chromatography results, and so on. The last layer in the result information storage text is used to store the last layer horizontal tomography results of the water vapor chromatography results.

[0038] Specifically, the wet refractive index or water vapor density is a direct reflection of the water vapor content in the atmosphere, and its value can indicate the spatial distribution characteristics of water vapor in the atmosphere. Therefore, using the wet refractive index to represent the results of water vapor tomography can intuitively understand the distribution of water vapor in three-dimensional space. Water vapor density refers to the mass of water vapor per unit volume, and its value directly reflects the content of water vapor in the atmosphere. Using water vapor density to represent the results of water vapor tomography has a clear physical meaning and is easy to understand and apply.

[0039] For a diagram of tiered storage, see Figure 4 , the content of each layer of the water vapor tomography results mainly involves the three-dimensional spatial distribution information of water vapor in the atmosphere. Specifically, water vapor tomography technology uses the oblique path wet delay data of GNSS (Global Navigation Satellite System) to invert the vertical and horizontal distribution of water vapor content in the atmosphere, which is expressed as the spatial distribution of wet refractive index or water vapor density. In the tomography results, each layer usually represents the atmospheric water vapor content and distribution within a certain height range. By storing the tomography results in layers, data management is more orderly, which is convenient for subsequent data analysis and application. Specifically, the data of each layer of the tomography results includes:

[0040] 1. Vertical distribution information: Water vapor tomography results can show the water vapor content at different altitudes from the ground to high altitudes (usually up to the top of the troposphere). These layers can be divided according to research needs, for example, every few hundred meters or a few thousand meters is a layer. The water vapor content of each layer reflects the density of water vapor in the atmosphere within the altitude range.

[0041] 2. Horizontal distribution information: In addition to vertical distribution, water vapor tomography results can also provide the horizontal distribution of water vapor in each layer. This helps to understand the horizontal changes in water vapor, such as which areas have higher water vapor content and which areas have lower water vapor content, as well as the direction and speed of water vapor flow.

[0042] 3. Three-dimensional spatial structure: By integrating vertical and horizontal distribution information, water vapor tomography results can construct the three-dimensional spatial structure of water vapor in the atmosphere. This structure is of great significance for understanding meteorological processes such as atmospheric circulation, water vapor transport, and precipitation formation.

[0043] 4. Accuracy and resolution: The accuracy and resolution of water vapor tomography results depend on many factors, including the quality of GNSS observation data, the accuracy of the tomography model, the setting of constraint conditions, etc.

[0044] In a specific embodiment, the method further includes: the number, division, and distribution of the grids of the horizontal tomography results of each layer in the result information storage text are the same as the actual distribution, and the same map orientation and topological relationship are maintained. Specifically, maintaining the consistency of the grids of each layer and the continuity of the topological relationship can ensure that the data is seamlessly connected between different levels and reduce the errors caused by inconsistent data. Through the grid division consistent with the actual distribution, the spatial position and form of the geographic entity can be more accurately reflected, and the accuracy of data analysis can be improved. Geographic data from different sources and scales can be integrated through consistent grid division and topological relationship to form a comprehensive data set, which is convenient for the fusion and utilization of multi-source data. Consistent grid division and topological relationship are conducive to the standardization and sharing of data, reduce the difficulty of data exchange and processing, and promote the sharing and interoperability of geographic information resources. Maintaining the same grid division and map orientation as the actual distribution can make the map expression more intuitive and accurate, and easy for users to understand and use. In the process of map making and visualization, consistent grid division and topological relationship help to improve the beauty and readability of the map and enhance the visual effect of the map. When the actual geographic distribution changes, maintaining consistent grid division and topological relationships can simplify the data update process and reduce update costs.

[0045] In a specific embodiment, the covariance matrix is ​​written into the first precision information storage text in matrix form, and each element in each covariance matrix in the first precision information storage text occupies a first number of storage bits. Specifically, the off-diagonal elements in the covariance matrix represent the linear correlation between the variables in the water vapor tomography results (such as water vapor density, wet refractive index, etc. at different heights or positions). Positive values ​​represent positive correlation, negative values ​​represent negative correlation, and zero values ​​or values ​​close to zero represent no linear relationship between variables. This intuitive display helps to quickly understand the interaction between variables. The diagonal elements of the covariance matrix are actually the variances of the variables, reflecting the accuracy of each variable. By looking at the diagonal elements, the stability or variability of each water vapor variable itself can be understood.

[0046] In a specific embodiment, after the observed value mean error vectors are written into the first precision information storage text one by one in element order, each line in the second precision information storage text contains at most 100 mean errors, and each mean error occupies 7 characters. Each element represents the mean error value of the corresponding observed value, which facilitates quantitative analysis and comparison of the relationship between the observed error and the result accuracy.

[0047] Specifically, the accuracy information part mainly stores the covariance matrix and mean error of the tomography results and observations. First, the covariance matrix of the tomography results is written directly in matrix form, with each element occupying 6 bits, including 1 decimal place; then the standard deviation of the observations is stored in matrix form, with each row containing a maximum of 100 elements. If there are more than 100 elements, the row will be wrapped, and each element occupies 7 bits, including 1 decimal place, until all standards have been written.

[0048] In a specific embodiment, the specific implementation method of the water vapor chromatography result storage method is:

[0049] Step 1: The header file (header information) starts with "#+comment name", and each line describes a comment content. This part mainly includes the grid division of the tomography grid in the south, north, and high directions, the start time of the observation data, the end time of the observation data, the number of valid rays, the total number of grids, the source of prior information, constraint information, processing mode, tomography algorithm, etc.

[0050] Step 2: The result information part mainly stores the Beidou water vapor tomography results. The results can be expressed by wet refractive index (unit: mm / km) or water vapor density (unit: g / m3), and are stored in a layered form. Each layer corresponds to a horizontal tomography result of one layer. The number, division, and distribution of grids are the same as the actual distribution, and the same map orientation and topological relationship are maintained. The first to last layers in the file correspond to the bottom to the highest layer of the Beidou three-dimensional water vapor tomography results.

[0051] Step 3: The accuracy information part mainly stores the covariance matrix and mean error of the tomography results and observations. First, the covariance matrix of the tomography results is written directly in matrix form, with each element occupying 7 bits, including 1 decimal place; then the standard deviation of the observations is stored in matrix form, with each row containing up to 100 elements. If there are more than 100 elements, the row will be wrapped, with each element occupying 7 bits, including 1 decimal place, until all standards have been written.

[0052] In the above step 1, the header file mainly stores information such as grid division, time information, data processing strategy, etc. during Beidou water vapor tomography, including some required parameters and some non-required parameters. The required parameters include: "#Grid division", "#N-Planes", "#E-Planes", "#U-Planes", "#Station center coordinates", #Result type:, non-required parameters include but are not limited to "#Observation start time", "#Observation end time", "Number of valid rays", "#Prior information", "#Constraints", "#Processing mode", "#System used", "#Tomography algorithm", "#Processing time:", etc. All parameter labels start with "#" and end with a colon, followed by specific parameters. Each parameter label and parameter occupies one line. The parameter format is shown in the following table:

[0053]

[0054]

[0055]

[0056]

[0057] Table 1: Header information parameter format

[0058] In step 2, the result information part mainly stores the Beidou water vapor tomography results. Assuming that the horizontal grid is divided into N×E grids during tomography, N in the north-south direction and E in the east-west direction, and the vertical direction is divided into U layers, from the bottom to the top, they are L1, L2, ..., LU. Then, the results of the L1 layer are first stored in this part, that is, N×E floating point numbers, and the horizontal distribution is consistent with the actual grid division. The map direction of north at the top, south at the bottom, west at the left, and east at the right is still maintained. After the N×E floating point numbers of the L1 layer are written, the L2 layer is written next, and so on, until the Lu layer. Each floating point number maintains 7 digits, including 1 decimal point, and the format is 7.1f. If the value is wet refractive index, the unit is mm / km; if the value is water vapor density, the unit is g / m3.

[0059] In step 3, the accuracy information file mainly stores the covariance matrix of the tomography results. Assuming there are N×E×U grids, the covariance matrix should be (N×E×U)2 , just write it to the file in the form of a covariance matrix. The format of each data is 7 digits, including 1 decimal place, and the format is 7.1f. After writing the covariance matrix, write the mean error list of the observations, keep 100 data in each line, and wrap the line if more than 100 until all the data are written. The format of each data is 7 digits, including 1 decimal place, and the format is 7.1f.

[0060] The following content is only for understanding this technology. Water vapor tomography is a technology that uses Beidou / GNSS observations to invert three-dimensional water vapor distribution. During the execution of this technology, the troposphere space is usually divided into three-dimensional grids, such as 10*10 grids in the horizontal direction, and then divided into 20 layers in the altitude layer, so that 2000 grids are obtained. The tomography technology uses Beidou / GNSS observation data to invert the wet refractive index or water vapor density in these 2000 grids (the two are convertible). The purpose of this application is to design a format to store tomography results. According to the example given, the wet refractive index or water vapor density of these 2000 grids is stored. In addition to storing data, basic information of data processing and geographic information of the grid are also stored (this requires that the grid must be informed of how it is divided) so that the results can correspond to a specific geographic space.
