Embodiment 1

[0057] see figure 1 , shows the precipitation data quality control method in the first embodiment of the present invention, which can be applied to precipitation data quality control equipment, and the precipitation data quality control equipment can be realized by software and / or hardware, and the method specifically includes Step S01 to step S05.

[0058] In step S01, the observed precipitation data obtained by ground station observation and the radar precipitation data obtained by radar detection are acquired.

[0059] Among them, ground stations include but are not limited to meteorological stations and hydrological stations. Ground stations such as meteorological stations and hydrological stations will be equipped with sensors capable of collecting precipitation data, so as to upload the precipitation data observed by corresponding stations in real time. At the same time, the radar will also conduct real-time detection of space precipitation to obtain radar precipitation...

Embodiment 2

[0088] The second embodiment of the present invention proposes a method for quality control of precipitation data. The method for quality control of precipitation data in this embodiment can be specifically applied to the following scenarios: use the weather station in Jiangxi Province after the business quality control at 15:00 on December 14, 2020 Taking observed precipitation, original hydrological station observed precipitation and original radar estimated precipitation as examples, multi-source precipitation collaborative quality control processing is performed according to the technical solution of the present invention. At that time, there were 2543 meteorological stations and 1767 hydrological stations, and the resolution of precipitation estimated by radar was 0.01°×0.01°. The precipitation data quality control method among the present embodiment specifically includes:

[0089] Step 1: Use the inverse distance weight interpolation method to perform spatial interpolati...

Embodiment 3

[0109] Another aspect of the present invention also provides a precipitation data quality control device, please refer to Figure 4 , shows the precipitation data quality control device in the third embodiment of the present invention, and the quality control device includes:

[0110] The data acquisition module 11 is used to acquire the observed precipitation data obtained by ground station observation and the radar precipitation data obtained by radar detection;

[0111] The data conversion module 12 is used to convert the observed precipitation data into gridded surface field precipitation data consistent with the spatial range and spatial resolution of the radar precipitation data;

[0112] The data correction module 13 is used to compare and analyze the ground field precipitation data and the radar precipitation data grid by grid, screen abnormal radar precipitation data, and obtain corrected radar precipitation data;

[0113] The data determination module 14 is used to ...

Abstract

The invention provides a rainfall data quality control method and device, a storage medium and equipment. The method comprises the steps that observation rainfall data obtained through ground station observation and radar rainfall data obtained through radar detection are obtained; performing grid-by-grid comparative analysis on the ground field rainfall data and the radar rainfall data, and screening abnormal radar rainfall data to obtain corrected radar rainfall data; determining radar rainfall data of each ground station based on the corrected radar rainfall data; and performing quality control processing on observation rainfall data obtained by observation of the ground station by using radar rainfall data of the ground station. Through collaborative application of multi-source rainfall data and a space-time multi-scale quality control technology, the problem of uncertainty of a single data source is effectively solved, the rainfall data quality control effect and precision are further improved on the basis of guaranteeing real-time quality control processing time efficiency, a more accurate live rainfall data source is obtained, and the real-time rainfall data quality control method is suitable for popularization and application. And a foundation is laid for subsequent data processing and application analysis.

Description

technical field [0001] The invention relates to the technical field of meteorological data quality control, in particular to a precipitation data quality control method, device, storage medium and equipment. Background technique [0002] The quality control of raw meteorological data is an essential link in the processing of meteorological data products, and its quality control effect directly affects the application and service quality of meteorological data. Among them, the quality control of precipitation data refers to the quality control of precipitation data to determine its quality status, with the focus on detecting error data to ensure that subsequent users can use accurate and high-quality data for weather forecasting, for example. [0003] At present, the meteorological data quality control business in China is mainly handled by the Meteorological Data Operation System (MDOS). MDOS can realize real-time and historical integrated quality control processing of mete...
