Embodiment Construction

[0061] Attached below figure 1 The present invention will be specifically described.

[0062] Based on the data of 9 S-band radars in Jiangsu Province from June to July 2016 and the conventional ground observations in the corresponding time period, the invention is used to perform fusion processing of multi-source observation data. First, the radar base data and conventional ground observation data are processed into the required format for fusion; then the multi-source fusion algorithm is used to take the preprocessed data as input to obtain the fused atmospheric three-dimensional grid data. Further use the fusion product to compare with the source data to test the fusion effect

[0063] 1. Data processing

[0064] · Conventional surface observation data processing

[0065] Conventional surface observation data are divided into two categories, one is the observation data of national observation stations, and the other is the observation data of local and regional observati...

Abstract

The invention discloses an NRIET meteorological multi-source detection data fusion analysis system, including data collection: acquiring various meteorological data of ground, high-altitude conventional observation, satellite, radar remote sensing observation and model background field. Data quality control: Perform quality control processing on various observation data collected. Data normalization processing: normalize the data for quality control, and provide a unified standard data interface for subsequent modules to call. Background field grid interpolation: Interpolate the model input as a background field to the 3D grid to obtain 3D background data. Multi-source data fusion: Use observation data to fuse and correct 3D background data. Fusion analysis: On the basis of fusion data, ground analysis, temperature analysis, cloud analysis, water vapor analysis and balance analysis are further used to further correct and perform diagnostic analysis. 3D meteorological information display and analysis: display the 3D grid point data of fusion analysis and provide interactive analysis functions.

Description

technical field [0001] The invention relates to a fusion analysis system of meteorological multi-source observation and detection data, in particular to a fusion analysis system of meteorological multi-source detection data. Background technique [0002] In recent years, the rapid development of my country's social economy has also brought opportunities for the development of meteorological observation systems. Meteorological detection technology has been continuously improved, and atmospheric detection equipment has been continuously increased. Not only has a new generation of weather radar network, FY-2E, FY-2F, FY-3A, FY-3B meteorological satellite observation network and ground automatic weather station observation network all over the country been established. , some emerging observation instruments, such as wind profilers, RASS radio-acoustic air profilers, GPS water vapor, microwave radiometers and other observation networks are also under construction, which greatly ...
