The GHRC DAAC has published the GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/HIWRAP/DATA101). The Olympic Mountain Experiment (OLYMPEX) was the final Global Precipitation Measurement (GPM) mission Ground Validation field campaign. HIWRAP is a Doppler radar designed to measure tropospheric winds through deriving Doppler profiles from cloud and precipitation volume backscatter. (Li et al. 2016). The winds are generated by combining conical scan mode measurements at two different frequency bands (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). HIWRAP utilizes solid state transmitters along with a novel pulse compression scheme resulting in a system that is considerably more compact and requires less power than typical radars used for precipitation and wind measurements. A more detailed description of the HIWRAP system and system parameters can be found in Li et al., 2016. More information about the HIWRAP instrument can be found at the Goddard Space Flight Center High Altitude Radar Group: https://har.gsfc.nasa.gov/index.php?section=13.
