Cimel Sunphotometer (CSPHOT) Spectral Deconvolution Algorithm (SDA) Retrieval Version 4.1 Level 1.0

The olicsphotsdav3M1.a1 datastream contains aerosol optical depth measurements from a Cimel Sunphotometer, which is a multi-channel, automatic sun-and-sky scanning radiometer that measures direct solar irradiance and sky radiance at the Earth's surface. This instrument takes measurements at predetermined discrete wavelengths in the visible and near-infrared parts of the spectrum to determine atmospheric transmission and scattering properties. The data were collected at Facility M1 (Oliktok Point, Alaska; AMF3), which is located at the OLI site (Oliktok Point, AK, USA; Long-term Mobile Facility) between September 23, 2013, and October 12, 2013.
