CoSSIR
Configurable Scanning Submillimeter-wave Instrument/Radiometer

The Configurable Scanning Submillimeter-wave Instrument/Radiometer (CoSSIR) is an airborne imaging radiometer designed to measure ice clouds. It measures brightness temperature across 16 channels in the 183-874 GHz range. These measurements can determine ice cloud properties, water vapor profiles, and snowfall rates. CoSSIR has a surface footprint of 1.5 km at nadir at an altitude of 20 km. It has a scan cycle of 4.6 seconds.
