The Far Infrared Sensor for Cirrus (FIRSC) is a remote passive airborne infrared spectrometer. It uses Fourier transform spectroscopy (FTS) to measure the infrared radiance of cirrus clouds. FIRSC operates across two channels with a wavenumber range of 10-35 per centimeter and 80-135 per centimeter. FIRSC has a field of view of 0.03 radians, a footprint of less than one kilometer, and a scan time of 4 seconds.
