Product Summary
GPM/DPR DPR Environment Auxiliary dataset is produced by the Japan Aerospace Exploration Agency (JAXA). Environment Auxiliary (ENV) is Meteorological analysis data used as an input data to the level 2 processing shown. They are the Japanese Global Analysis model data (GANAL) used to provide atmospheric environmental conditions.
In the current algorithm formulation, only the analysis data such as analysis data, must be integrated from an external source during combined algorithm processing. Analysis data are required to produce initial estimations of environmental parameters such as total precipitable water, TPWanal, cloud liquid water path, CLWPanal, surface skin temperature, Tsfcanal, and 10m altitude wind speed, U10manal. The current algorithm design requires space-time interpolation of these data from the Japanese Meteorological agency’s (JMA) global analysis (GANAL) during standard algorithm processing. The data are interpolated to the DPR footprint/range bin locations and overpass times in the Vertical Profile Submodule (VER) of the Level 2 Radar Algorithm and then output. For near realtime processing, the JMA forecast fields, but if these fields are not received in time for any reason, the climate value data are substituted for the JMA analysis/forecast data in the VER processing.
