SWS
Shortwave Spectroradiometer

The Shortwave Spectroradiometer (SWS) is a radiometer that measures absolute visible and near-infrared spectral radiance. It includes two Zeiss spectroradiometers to measure spectral radiance, which are used to determine cloud optical depth, particle size, and water path. One spectroradiometer operates in the 300-1100 nm wavelength range at a spectral resolution of 8 nm, while the other operates in the 900-2200 nm range at a resolution of 12 nm. SWS has a sampling frequency of 1 Hz. The Department of Energy’s Atmospheric Radiation Measurement (ARM) User Facility operated a ground-based SWS, and the Facility for Airborne Atmospheric Measurements (FAAM) operated an airborne version as part of the airborne laboratory.
