The Scanner for Radiation Budget (SCaRaB) is a joint project of France, Germany and Russia and was flown on Russian Meteor-3/7 spacecraft in 1994/1995. The main goal of the ScaRaB instrument is to study the Earth's radiation budget and cloud-radiation interactions. The ScaRaB instrument is a cross-track scanning radiometer with a 60x60 km2 field of view and the pixel spacing is on a square grid of 42.5 km at nadir. The ScaRaB radiometer consist of four parallel telescopes. These are identical except for the optical filters. Each telescope represents one spectral channel: visible, solar, total and atmospheric window. 1 Visible Channel: 0.55 - 0.65 5m 2 Solar Channel(SW): 0.20 - 4 5m 3 Total Channel(TW): 0 20 - 50 5m 4 Window Channel: 10.5 - 12.5 5m Radiation in the Thermal Longwave band (4-50 5m) is determined from the measurements in Channel 2 and 3. The narrower channels 1 and 4 are to be used as a link to operational imager channels and to aid in cloud scene identification.
