RASICAM

As a radiometric all-sky infrared camera (RASICAM) is optimized to detect the position, motion and optical depth of thin, high (8-10 km) cirrus clouds and contrails by measuring their apparent temperature above the night sky background. The camera system utilizes a novel wide-field equi-resolution catadioptric mirror system that provides sky coverage of 360º in azimuth and 14-90° from zenith.
