Instrument

CAR
Cloud Absorption Radiometer

The Cloud Absorption Radiometer (CAR) is an airborne multi-wavelength scanning radiometer developed by Goddard Space Flight Center (GSFC). CAR provides measurements of scattered radiance and bidirectional reflectance of the surface across 14 spectral bands in the visible and near-infrared wavelengths (0.34-2.30 µm). It also acquires imagery of cloud and Earth surface features. CAR has a scan rate of 1.67 Hz (100 rpm) and has a spatial resolution of 4m at nadir for an altitude of 200m above ground level.
