The Conical Scanning Submillimeter-wave Imaging Radiometer (CoSSIR) is a passive remote imaging radiometer. It has been flown on multiple aircraft since its development, including NASA’s ER-2 aircraft. CoSSIR was designed to take measurements of ice clouds and brightness temperatures. Its measurements can also be used to estimate water vapor profiles and snowfall rates. CoSSIR has a surface footprint of 1.4 km at nadir. It completes a scan cycle every 4.6 seconds. CoSSIR has 12 channels and operates in the 183-874 GHz range.
