HURRICANE AND SEVERE STORM SENTINEL (HS3) GLOBAL HAWK HIGH ALTITUDE MMIC SOUNDING RADIOMETER (HAMSR) V1

The Hurricane and Severe Storm Sentinel (HS3) Global Hawk High Altitude MMIC Sounding Radiometer (HAMSR) dataset includes measurements gathered by the HAMSR instrument during the HS3 campaign. Goals for HS3 included: assessing the relative roles of large-scale environment and storm-scale internal processes; and addressing the controversial role of the Saharan Air Layer (SAL) in tropical storm formation and intensification as well as the role of deep convection in the inner-core region of storms. HAMSR has 25 spectral channels which are split into 3 bands: an 8-channel band centered 53-GHz, used to infer the 3-D distribution of temperature; a 10-channel band centered at 118 GHz, used for secondary temperature sounding and assessment of scattering; and a 7-channel band centered at 183 GHz, used to measure water vapor (humidity) and cloud liquid water content in the atmosphere. This dataset also contains measurements that can be used to infer the 3-dimensional distribution of temperature, water vapor, and cloud liquid water profiles in the atmosphere, even in the presence of clouds. HAMSR is mounted in payload zone 3 near the nose of the Global Hawk NASA aircraft. Data is available in netCDF/CF format.
