Active Cavity Radiometer Irradiance Monitor-3 (ACRIM-3)
The Active Cavity Radiometer Irradiance Monitor Satellite, or ACRIMSAT was a satellite carrying the ACRIM-3 (Active Cavity Radiometer Irradiance Monitor 3) instrument. It was one of the 21 observational components of NASA's Earth Observing System program. The instrument followed upon the ACRIM-1 and ACRIM-2 instruments that were launched on multi-instrument satellite platforms. ACRIMSAT was launched on 20 December 1999 from Vandenberg Air Force Base as the secondary payload on the Taurus launch vehicle that launched KOMPSAT. It was placed into a high inclination of 98.30°, at 720 km. Sun-synchronous orbit from which the ACRIM-3 instrument monitored total solar irradiance (TSI).[3] Contact with the satellite was lost on 14 December 2013.[4]
