  1. National Weather ServiceForecast Evolution and Delivery in a Digital Era Glenn Austin Office of Climate, Water, and Weather Services Dave Ruth Office of Science and Technology National Digital Forecast Database Technical Workshop November 2, 2006 NOAA/NWS Digital Services

  2. National Digital Forecast Database • GOAL: Make NWS information available electronically in digital form. • HISTORY: NDFD has been operational since 2004. NOAA/NWS Digital Services

  3. Internet-based Services • e-Gov and e-commerce are supported with: • File Dissemination Services • XML Web Service • Web Graphics • GIS (decoder/encoder) • Archive Access System NOAA/NWS Digital Services

  4. Geographic Domains • CONUS • Mosaic • 16 pre-defined sectors • User-defined areas • OCONUS • Alaska • Hawaii • Guam • Puerto Rico/V.I. NOAA/NWS Digital Services

  5. File Dissemination • Data posted in WMO GRIB2 format at: • ftp://tgftp.nws.noaa.gov/SL.us008001/... • Decoder software: http://www.weather.gov/mdl/NDFD_GRIB2Decoder • Function: Allows download and conversion to: • Shape files (compatible with ESRI) • Points, Simple polygons, Merged polygons • netCDF • GrADS • Lat/lon grids, Projected grids • Float files • Comma Separated Values files NOAA/NWS Digital Services

  6. Experimental elements: QPF Snow Amount Sky Cover Significant Wave Height Probability of Tropical Cyclone Wind Speeds Wind Gust Operational elements: Maximum Temperature Minimum Temperature Temperature Dew Point Probability of Precipitation Weather Wind Direction Wind Speed Apparent Temperature Relative Humidity NDFD StatusNow available at ftp://tgftp.nws.noaa.gov/SL.us008001/... ST.opnl/DF.gr2/DC.ndfd/ ST.expr/DF.gr2/DC.ndfd/ Note: Six Alaska NDFD elements are currently experimental. NOAA/NWS Digital Services

  7. Technical Releases • Day 1-3/4-7 file split • Effective September 6, 2006 • Announced in TIN 06-30 issued May 9, 2006 • Adjust time NDFD is extended 24 hours to 22Z • November 28, 2006 • Announced in TIN 06-72 issued Oct 23, 2006 NOAA/NWS Digital Services
