3D Wind Field Retrieval Applied to Snow Events Using Doppler Radar

The variational analysis method of Laroche and Zawadzki for the retrieval of the 3D wind field from single-Doppler radar data is adapted to analyze stratiform snow events. Modifications include prefiltering of noisy radial velocity data using a velocity azimuth display (VAD) analysis, the use of sno...

Description
Summary:The variational analysis method of Laroche and Zawadzki for the retrieval of the 3D wind field from single-Doppler radar data is adapted to analyze stratiform snow events. Modifications include prefiltering of noisy radial velocity data using a velocity azimuth display (VAD) analysis, the use of snow particle fall speeds derived from extended VAD analyses, and the usage of high-elevation angle data.
