ACRIM III Data Sets

Active Cavity Radiometer Irradiance Monitor (ACRIM) III monitors the total variability of solar irradiance with active cavity radiometer solar monitoring sensors. ACRIM III was successfully launched on board the ACRIMSAT spacecraft on December 20, 1999.

ACRIM III data are reprocessed every 90 days to utilize instrument recalibration.
