MCR
Multichannel Cloud Radiometer

The Multichannel Cloud Radiometer (MCR) is an airborne passive radiometer originally developed by Goddard Space Flight Center (GSFC) and later transferred to NCAR’s Research Aviation Facility (RAF). It operates across seven channels (0.640-10.9 μm) to measure radiance in the visible, near-infrared, and thermal infrared. These measurements are used to retrieve cloud properties, including cloud optical depth, cloud droplet size, cloud phase, and cloud temperature. The MCR has a field of view of 0.007 radians and a data sampling rate of 5000 samples per second.
