Abstract

The embodiment of the invention discloses an estimation and correction method and device for air sounding observation data. For each air pressure layer involved in to-be-estimated target air soundingobservation data, the evaluation parameters for evaluating the quality of the air sounding observation data of the air pressure layer through the second air sounding observation data observed at the air pressure layer and corresponding mode background data, and the evaluation and correction of the quality of the target air sounding observation data are performed through the evaluation parameters,so as to improve the quality of air sounding observation data. The method achieves the joint evaluation of the quality of the air sounding observation data of the same air pressure layer through the evaluation parameters, and the evaluation result is more accurate. Meanwhile, the method achieves the correction of the air sounding observation data through the evaluation parameters, enables the airsounding observation data to be more reasonable and facilitates the application of the data into an experiment or weather analysis.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radiosonde data processing, and in particular to a method and device for evaluating and correcting radiosonde observation data. Background technique [0002] The existing processing of sounding data is based on the background field provided by the numerical forecast assimilation system, and the difference between the observation data and the background field is calculated (referred to as the observation residual); the quality control of the observation data is carried out to exclude abnormal values; statistical analysis of various The acceptance rate of observation reports, the spatial and temporal distribution of observation reports, the ratio of outliers, the average deviation and standard deviation of observation residuals, etc. For example, the global observation data quality monitoring and evaluation system uses the 6-hour forecast field as the background field of data assimilat...
