GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) OLYMPEX V1a

Metadata Updated: August 9, 2018

The High Altitude Wind and Rain Airborne Profiler (HIWRAP) instrument 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. HIWRAP was originally designed to fly on the NASA Global Hawk, but was since modified to fly on the NASA ER-2 with a fixed nadir pointing configuration as part of RADEX, a field campaign coordinated with OLYMPEX designed to develop algorithms for the ACE Decadal Mission Ka-/W-band Doppler radar. A more detailed description of the HIWRAP system and system parameters can be found in Li et al., 2016. More information about HIWRAP can be found at the Goddard Space Flight Center High Altitude Radar Group: https://har.gsfc.nasa.gov/index.php?section=13.
