[AAS01-02] Ground validation of EarthCARE/Cloud Profiling Radar using WINDAS data
キーワード：アースケア衛星、雲プロファイリングレーダー、気象庁ウィンドプロファイラネットワーク
Earth Cloud Aerosol and Radiation Explorer (EarthCARE) satellite is planning to launch in May 2024. Cloud Profiling Radar (CPR) is one of sensors installed in this satellite and vertical profile of clouds and its vertical velocity can be measured by CPR, W-band (94GHz) Doppler cloud radar. In order to validate EarthCARE/CPR data after launch, cloud and rain observation with vertical pointing ground radars are expected during the EarthCARE satellite passing. Observation by cloud radars is preferable for validation of CPR, but cloud radars are few and simultaneous observation opportunity is limited.
WINDAS is a Japanese wind profiler network of Japan Meteorological Agency. 31 of wind profilers have been operated since 2003 from north to south of Japan. (33 of wind profilers are operated now.) High altitude wind data observed by the WINDAS are used for numerical weather prediction as complemental usage of radiosonde. Since its frequency is rather high (1.357 GHz), not only atmospheric turbulent echoes but also ice cloud and precipitation echoes are available in WINDAS as targets for wind estimation. We are thinking to use ice cloud echoes observed by WINDAS for validate CPR doppler measurement.
We made a rough method to separate atmospheric echoes and cloud and precipitation echoes using vertical velocity and echo intensity observed by the WINDAS along with its height and temperature information. Here, we will show some statistics of vertical velocity of ice particle observed by several WINSDAS sites.
