Problems solved by technology

[0004] However, since the forecast model field data is not real data, it is unreliable to compare it with the occultation data as the background field data, and the erroneous data in the occultation data is eliminated simply based on a certain judgment basis, and the correct data is prone to be eliminated situation, reducing the accuracy of quality control on occultation data

Embodiment 1

[0056] figure 1 It is a flow chart of a method for quality control of occultation data provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of quality control of occultation data, and the method can be executed by a quality control device for occultation data , the device can be composed of hardware and / or software, and generally can be integrated in various general-purpose computer equipment, specifically including the following steps:

[0057] Step 110: Divide the matched occultation data and the sounding data corresponding to the matched occultation data according to the pressure layers to obtain the occultation data and sounding data corresponding to each pressure layer.

[0058] Wherein, the occultation data is the data obtained by inverting the signal acquired in the occultation event. Generally, an occultation event refers to an event in which two star bodies that were originally visible directly in space are covered by othe...

Embodiment 2

[0088] figure 2 It is a flowchart of a quality control method for occultation data provided by Embodiment 2 of the present invention. This embodiment is further refined on the basis of the previous embodiment, and provides a method for determining the correctness of the target occultation data based on the correlation coefficient. The specific steps of the data, and the data ranges of the first erroneous data, the first suspicious data, the second erroneous data, and the second suspicious data. Combine below figure 2 A method for quality control of occultation data provided in Embodiment 2 of the present invention is described, including the following steps:

[0089] Step 210: Divide the matched occultation data and the sounding data corresponding to the matched occultation data according to the pressure layers to obtain the occultation data and sounding data corresponding to each pressure layer.

[0090] Step 220: Divide the occultation data and sounding data correspondin...

Embodiment 3

[0127] Figure 3a It is a flow chart of a quality control method for occultation data provided by Embodiment 3 of the present invention, and this embodiment is a preferred embodiment of the present invention. A method for quality control of occultation data provided by Embodiment 3 of the present invention will be described below in conjunction with FIG. 3 , including the following steps:

[0128] Step 310, acquiring occultation data and latitude and longitude data of multiple sounding stations; wherein, the occultation data includes multiple sets of sampling data, and each set of sampling data includes latitude and longitude data.

[0129] Step 320: Use the position determined by the latitude and longitude data in each group of sampling data as the target position, and use the position determined by the latitude and longitude data of each radiosonde station as the reference position.

[0130] Step 330, for each reference position, determine at least one target position withi...

Abstract

The embodiment of the invention discloses an occultation data quality control method, device and equipment and a storage medium, and the method comprises the steps of dividing the matched occultationdata and the corresponding sounding data according to an air pressure layer and a region, and obtaining the target occultation data and the target sounding data; determining the first error data and the first suspicious data based on the double-weight coefficient of the target occultation data; removing the first error data in the target occultation data to obtain first residual data, and determining the deviation data of the first residual data and the target sounding data; determining the second error data and the second suspicious data based on the double-weight coefficient of the deviationdata; removing the occultation data corresponding to the second error data in the first residual data, and obtaining the second residual data; and determining a correlation coefficient of the secondresidual data and the target sounding data, and determining the correct data in the target occultation data based on the correlation coefficient. According to the embodiment of the invention, the reliability of the background field data and the accuracy of quality control of the occultation data can be improved.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular, to a quality control method, device, equipment, and storage medium for occultation data. Background technique [0002] With the continuous development of the satellite industry, occultation detection technology has become a technical means to effectively monitor or predict changes in the atmosphere. To control the quality of the obtained occultation data and obtain the correct data is to use occultation detection technology to carry out atmospheric important step in the analysis. [0003] In the prior art, the traditional standard deviation method and the double-weighted quality control method are mainly used, based on the occultation data itself and the background field data, by generating different judgment criteria and eliminating the erroneous data in the occultation data, so as to realize the accuracy of the occultation data. Among them, the background...
