NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Downward Shortwave Radiation: Surface (DSR)

ABI-L2-DSR

browse graphicExample of the Downward Shortwave Radiation (at the surface) product as generated by the GOES-R Downward Shortwave Radiation algorithm.
The Downward Shortwave Radiation: Surface product contains an image with pixel values identifying the instantaneous total shortwave irradiance (flux) received at the Earth's surface integrated over the 0.2 to 4.0 um wavelength bandpass. It includes contributions from direct solar radiation attenuated by the atmosphere and from diffuse radiation associated with scattering within
the atmosphere. The product includes data quality information that provides an assessment of the downward shortwave radiation: surface data values for on-earth pixels. The units of measure for the downward shortwave radiation: surface value is watts per square meter. The Downward Shortwave Radiation: Surface product image is produced on a global latitude/longitude grid at 0.5 degree resolution for Full Disk, 0.25 degree resolution for CONUS, and 0.05 degree resolution for Mesoscale 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 DSR has many applications both in the general and applied sciences. As one of the components of the surface energy budget, it is needed in climate studies. Used together with cloud and aerosol properties it provides estimates of cloud and aerosol effects (forcing). It is also used in surface energy budget models, land surface assimilation models such as those used at NOAA NCEP, NASA LDAS, and ocean assimilation models either as an input (providing observationally-based forcing term), or as an independent data source to evaluate model performance. DSR data are also employed in estimating heat flux components over the coastal ocean to drive ocean circulation models. In agriculture, DSR is used as input in crop modeling. In hydrology, it is used in watershed and run-off analysis, which is important for determining flood risks and dam monitoring. The solar energy industry also needs estimates of DSR for both real-time and short-term forecasts for building energy usage modeling and optimization. Since high irradiance values result in surface drying, DSR is also used in monitoring fire risk.

Processing Steps
  • The Downward Shortwave Radiation: Surface 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.
