The instruments studied in that workshop included the Active Cavity Radiometer Irradiance Monitor III (ACRIM III) on the Active Cavity Radiometer Irradiance Monitor SATellite (ACRIMSAT), the Total Irradiance Monitor (TIM) on the Solar Radiation and Climate Experiment (SORCE), the Variability of solar IRradiance and Gravity Oscillations (VIRGO) on the Solar and Heliospheric Observatory (SOHO), and the Earth Radiation Budget Experiment (ERBE) on the Earth Radiation Budget Satellite (ERBS).
Aside from SOHO, measurements of the Sun's total solar irradiance--the total energy from the Sun across different wavelengths--have mainly come from the Solar Maximum Mission, the Upper Atmosphere Research Satellite (UARS), Nimbus 7, the Earth Radiation Budget Satellite (ERBS), ACRIMSAT, and particularly the current Solar Radiation and Climate Experiment (SORCE) mission, which carries state-of-the-art solar radiometers that monitor both the total energy and spectrum.
ACRIMSat weighs 115 kilograms and carries a single instrument that measures the absolute solar flux from 2000 angstroms in the ultraviolet to 20,000 angstroms (2 microns) in the infrared.
