The GOES-R PLT Surface Radiance Red Lake dataset consists of surface radiation budget, ultraviolet-B (UVB) and photosynthetically active radiation (PAR) flux, meteorological (temperature, pressure, relative humidity, winds), and spectral aerosol optical thickness data collected by a mobile SURFRAD station at Red Lake, Arizona for the GOES-R Post Launch Test (PLT) field campaign. The campaign took place from March to May of 2017 in support of post-launch L1B and L2+ product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). Data files are available in ASCII text format from March 27, 2017 through April 12, 2017. Surface reflectance measurements based on spectroradiometer data are also included in Microsoft Excel format.
