NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Reflected Shortwave Radiation Top-of-Atmosphere

ABI-L2-RSR

browse graphicExample of the Reflected Shortwave Radiation (at the top of the atmosphere) product as generated by the GOES-R reflected Shortwave Radiation algorithm.
The Reflected Shortwave Radiation: TOA product contains an image with pixel values identifying the instantaneous total shortwave irradiance (flux) energing at the Earth's TOA integrated over the 0.2 to 4.0 um wavelength bandpass. It includes contributions from the solar radiation reflected upward by the Earth's surface and that scattered by the atmosphere. The product includes data quality information that provides an assessment of the reflected shortwave radiation: TOA data values for on-earth pixels. The units of measure for the reflected shortwave radiation: TOA value is watts per square meter. The Reflected Shortwave Radiation: TOA product image is produced on a global latitude/longitude grid at 0.25 degree resolution for Full Disk and CONUS coverage regions. Product data is produced for geolocated source data to local zenith angles of 90 degrees and solar zenith angles to 90 degrees.

Purpose The Reflected Shortwave Radiation product will measure the total amount of shortwave radiation that exits the Earth through the top of the atmosphere. The algorithm will use several spectral channels in both the visible and infrared spectrum to measure the Reflected Shortwave Radiation. Information from this product will provide an integral piece of the Earth's radiation budget, aiding in climate modeling and prediction.

Processing Steps
  • The Reflected Shortwave Radiation: TOA product is generated by the GOES-R ABI Downward Shortwave Radiation: Surface and Reflected Shortwave Radiation: TOA ground processing algorithm. Depending on the availability of inputs, the algorithm performs either a "direct" or "indirect" retrieval of broadband transmittance and reflectance over four scene types: clear sky over no snow/ice; clear sky over snow/ice; water cloud, and; ice cloud. The "direct" retrieval is primary method. Computed atmospheric transmittance and reflectance are used to derive the shortwave fluxes at the surface and TOA. The "direct" retrieval path uses ABI products to estimate fluxes from Level 2 processing parameter lookup tables whose values are based on a forward radiative transfer model. When inputs needed for the "direct" retrieval path are not available, the algorithm uses the "indirect" retrieval path, invoking a multistep inversion scheme. The "indirect" retrieval path includes the calculation of a clear-sky snow/ice-free compostite TOA albedo derived from the ABI reflectance observations over the previous 29 days. Both retrieval paths rely on primary inputs at 2 km resolution that are averaged over each scene type on the output global latitude/longitude grid. Grid cells within the product extent not represented by a direct mapping between the ABI fixed grid and the global latitude/longitude grid are assigned values based on the nearest neighbor. The coverage region included in the Full Disk and CONUS radiation products is the minimum bounding rectangle within the global latitude/longitude grid. In the case of the mesoscale coverage region, the radiation product data structure dimensions are fixed and based on its maximum latitude/longitude extent on the ABI Full Disk. Pixels in the product image with out of range values are assigned the minimum or maximum value in the valid range.
