SPACECARE (Study of Precipitation in the AntarctiC with EarthCARE)

Christophe

Genthon

CNRSFRANCE

This proposal addresses the validation of C-TC, C-CLR, ACM-CAP with a precipitation Radar in the Antarctic.

All microphysical parameters used by the EarthCARE algorithm to infer reflectivity-weighted fall speed will be directly compared to aircraft measurements. A further validation step is to model the storm at high-resolution, validate the model with aircraft data, and apply the model to the EarthCARE data to achieve statistical validation.
