Description

CER_FluxByCldTyp-Month_NOAA20-VIIRS_Edition1C is the Clouds and the Earth's Radiant Energy System (CERES) Monthly Daytime Mean Regionally Averaged NOAA-20 Top-of-Atmosphere (TOA) Fluxes and Associated Cloud Properties Stratified by Optical Depth and Effective Pressure Edition 1C data product. Data was collected using CERES Flight Model 6 (FM6) and Visible Infrared Imaging Radiometer Suite (VIIRS) on NOAA-20 Data collection for this product is ongoing.

CER_FluxByCldTyp-Month_NOAA20-VIIRS_Edition1C provides the monthly mean daytime CERES fluxes and CERES-VIIRS cloud properties that have been spatially gridded into 1° regions along the NOAA-20 ground track where the TOA fluxes and cloud properties have been stratified by six cloud optical depth bins and seven cloud effective pressure layers. The CERES FluxByCldTyp-Month Edition1C product uses Single Scanner Footprint (SSF) Edition1C footprint data as input. Within each footprint, all 1-km pixel-level VIIRS-retrieved cloud properties are stratified into three possible sub-footprint components: two cloud layers and a clear portion. For each sub-footprint component, the VIIRS channel radiances are converted to broadband (BB) radiances. The CERES angular directional models are then applied to obtain BB fluxes. Each of the CERES sub-footprint cloud layers and associated fluxes are assigned to one of the 42 cloud types, similarly to the stratification process in the CldTypHist product. FluxByCloudTyp is a monthly instantaneous gridded and averaged daytime-only product with a global extent. Each netCDF4 file covers a single day.

CERES is a key component of the Earth Observing System (EOS) program. The CERES instruments provide radiometric measurements of the Earth's atmosphere from three broadband channels. The CERES missions are a follow-on to the successful Earth Radiation Budget Experiment (ERBE) mission. The newest CERES instrument (FM6) was launched onboard the Joint Polar-Orbiting Satellite System 1 (JPSS-1) satellite, now called NOAA-20, on November 18, 2017.
