Research Abstract

This study aims to improve the vertical resolution of radar measurement by applying variational assimilation method to the oversampled radar data to implement the humidity estimation with the wind profiling radar with the higher precision. The conventional method to improve vertical resolution of radar measurement does not consider the radar parameter conservativeness, which is essential for the quantitative evaluation of radar data. Our newly developed algorithm is tested by the quasi-radar data generated from data of balloon measurement, showing the excellent performance of our method. We also aimed the improvement of humidity estimation with the radar in the aspect of the elucidation of generation mechanism in clear-air echo. The hyper-high-resolution radiosonde observation is conducted simultaneously with the radar measurement. The preliminary results shows the good coincide, and the further analysis is very promising to improve humidity estimation with the wind profiling radar
