HAMSR
High Altitude Monolithic Microwave integrated Circuit (MMIC) Sounding Radiometer
The High Altitude Monolithic Microwave integrated Circuit (MMIC) Sounding Radiometer (HAMSR) is an airborne microwave sounder developed by the Jet Propulsion Laboratory under the NASA Instrument Incubator Program. HAMSR measures brightness temperature which can be used to derive three-dimensional profiles of temperature, water vapor, and cloud liquid water in the atmosphere. It operates across 25 spectral channels in 3 microwave bands (50-60 GHz, 118 GHz, 183 GHz) and has a sampling frequency of 5 seconds. HAMSR has a horizontal spatial resolution of 2 km at nadir and a field of view of about 40 km at an altitude of 20 km.
