Sunphotometer Supports SPARTICUS Campaign and Satellite Validation Studies
To supplement airborne cirrus particle size measurements obtained during SPARTICUS, a Sun and Aureole Measurement (SAM) imaging sunphotometer is collecting ground-based radiance measurements at the ARM Southern Great Plains (SGP) site’s Central Facility. Measurements of the solar disk and aureole radiance profile at a wavelength of 670 nm are ideally suited to investigate the larger…
