Abstract

The invention relates to a satellite-ground raindrop spectrum parameter matching and evaluating method and system. The method comprises the following steps: S1, acquiring data from different data sources; S2, matching the data of different data sources; and S3, evaluating raindrop spectrum parameter data. According to the method, raindrop spectrum data products of a foundation, an empty foundationand a space foundation can be decomposed, the same element observed by different devices is sorted, and after single elements of multiple devices are subjected to quality control, for the same observation element, Matching cross validation analysis is carried out on direct observation and telemetry data of different observation platforms and different observation inversion methods, similarities and differences are analyzed, and finally analytical validation for instrument levels is established based on raindrop spectrum parameter data, so that high-quality raindrop spectrum parameter data andproduct support are provided for weather forecast and decision service. On the basis of verifying the data quality of the raindrop spectrometer network of the national ground meteorological station,not only is liquid rainfall analyzed, but also solid rainfall can be analyzed.

Description

technical field [0001] The invention belongs to the technical field of geographic information management, and in particular relates to a method and system for matching and evaluating parameters of satellite-earth raindrop spectrum. Background technique [0002] At present, my country's meteorological department has deployed more than 2,000 national-level ground weather station raindrop spectrometer networks, including 100 and 200 models, and it will be put into commercial application around the beginning of 2019. The radar can be retrieved from the ground raindrop spectrometer equipment Albedo factor (Z), precipitation intensity (R), mass-weighted mean diameter (Dm), and generalized intercept parameter (LgNw), with a time resolution of 1 min. my country's meteorological department has deployed more than 2,000 national-level surface weather stations, which can directly obtain hourly precipitation (R) with a time resolution of 1 hour. my country's meteorological department has...
