Title Polarimetric Radar Discrimination Between Small, Large, and Giant Hail at S Band.
Publication Date 2013
Media Count 13p
Personal Author A. Ryzhkov J. Picca
Abstract The previous version of the algorithm for hail detection and determination of its size which was delivered to the Lincoln lab in September 2010 aimed at discrimination between small (less than 2.5 cm) and large (more than 2.5 cm) hail using a set of thresholds involving radar reflectivity factor Z and differential reflectivity ZDR. Depending on the height of the radar resolution volume, different Z and ZDR thresholds have to be applied. A functional description of the previous algorithm is included herein.
