Cimel Sunphotometer (CSPHOT): aerosol optical depth, filtered data, version 3

The sgpcsphotaodfiltqav3S01.a1 datastream contains aerosol optical depth, aerosol optical properties, and precipitable water measurements from a Cimel Sunphotometer. 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 S01 (Supplemental 1, Lamont, OK), which is located at the SGP site (Southern Great Plains), between October 1, 2017, and May 4, 2018.
