ASD-FR
Analytical Spectral Devices Full Range Spectroradiometer

The Analytical Spectral Device Full Range (ASD-FR) is a ground-based passive spectroradiometer manufactured by Malvern PANalytical. It measures reflectance, transmittance, radiance, and irradiance spectra of vegetation, soils, rocks, and bodies of water. It operates across the entire solar irradiance spectrum (350-2500 nm). It has a spectral resolution of 3 nm in the visible and near-infrared (VNIR) region and 8 nm in the shortwave infrared (SWIR). The ASD-FR is used to collect ground truth data, support geological research, study plant physiology and ecology, and support other atmospheric remote sensing applications.
