Assessing 94-GHz Radar Estimates in Polar Regions through the K2W Methodology

A methodology for estimating reflectivity and Doppler velocity at 94 GHz from K-band Doppler spectra collected by MRR and coincident disdrometer observations has been developed and tested in Antarctica using CloudSat overpass. This methodology, called K2W, is now evaluated in Artic, at the Ny Ålesund AWIPEV French-German research base using a co-located W-band. The three cases of snow precipitation analyzed highlight a fairly good performance of K2W.
