The provision of NDFD and Air Quality data via AWS will enable users to access all existing operational and experimental NDFD and Air Quality NDGD data at the finest temporal and spatial resolutions in GRIdded Binary data Edition 2 (GRIB2), image/display, and eXtensible Markup Language (XML) format. Full resolution map images of NDFD will be available at the same graphical.weather.gov and digital.weather.gov URLs which show lower resolution images now. Some bookmarks that specify page options via the URL may need to be updated. NDFD XML data currently available at graphical.weather.gov/xml and digital.weather.gov/xml will be available at the same URLs, but with finer temporal and spatial resolution than is currently available operationally. No changes to the XML query strings should be required to access these data at full resolution. URLs for the current full-resolution prototype sites (https://digital.mdl.nws.noaa.gov, https://graphical.mdl.nws.noaa.gov, and https://digital.mdl.nws.noaa.gov/airquality) will redirect to operational sites of https://digital.weather.gov/, https://graphical.weather.gov/ and https://airquality.weather.gov/. In addition, full-resolution NDFD element images can now be accessed via Web Map Services (WMS). Click on the NDFD Data link along the bottom of the map image to learn how to do this.
