High-resolution radar data and products over the Continental United States
In this paper, we describe two possible architectures -- networking, hardware and software -- to suit different decision-support needs: (1) a single-machine architecture where end users change, in real-time, their domain of interest and start receiving data and products corresponding to that domain in a matter of minutes (2) a networked architecture, where the WDSS-II system operates on data from the entire CONUS. The first architecture was tested at the Storm Prediction Center (SPC) during spring and fall 2004 and the second architecture will be tested at the SPC in fall 2005. With a fixed domain, the first architecture was used to supply grids to the AWIPS of selected National Weather Service Weather Forecast Offices (NWS WFOs) starting spring 2005.
In the CONUS-wide real-time system that we describe here, the radar products are rapidly updated every 2 minutes from elevation scans as they arrive from any radar in the country. The resulting products are at a resolution of approximately 1km x 1km x 1km. These products can be disseminated as GeoTiff, NetCDF and/or Grib2 files for easy incorporation into other decision-support and visualization systems.
