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

The tmpcsphotsdav3M1.a1 datastream contains aerosol optical depth measurements from a Cimel Sunphotometer using the Spectral Deconvolution Algorithm (SDA) Retrieval, Version 4.1, Level 1.0. This instrument is a multi-channel, automatic sun-and-sky scanning radiometer that measures direct solar irradiance and sky radiance at the Earth's surface at predetermined discrete wavelengths in the visible and near-infrared parts of the spectrum. The data were collected at Facility M1 (U. of Helsinki Research Station, Hyytiala, Finland; AMF2), which is located at the TMP site (Hyytiala, Finland; Mobile Facility for BAECC), between January 21, 2014, and March 25, 2014.
