CEOS Instrument: Active Cavity Radiometer Irradiance Monitor

Instrument:ACRIM III
Agency: NASA
Type:Solar irradiance monitor
Description:Measurements of solar luminosity and solar constant. Data used as record of time variation of total solar irradiance, from extreme UV through to infrared
Spatial Resolution: 5 deg FOV
Swath Width: 71 mins per orbit of full solar disk data
Wavebands: UV - MWIR: 0.15 - 5 ?m
Technology: Solar irradiance monitor
Description: Observes radiation coming from the Sun, either integrated (i.e., in the interval 0.2-10 Ám, observed by cavity radiometers) or spectrally resolved (e.g., in the interval 0.2-2 Ám, observed by a spectrometer), or for special features (X-rays, UV, etc,). Applicable in LEO and GEO.
