National Digital Forecast Database (DSI-9959)Entry ID: gov.noaa.ncdc.C00595
Abstract: National Digital Forecast Database (DSI-9959) is a digital data set archived at the National Climatic Data Center (NCDC). The National Digital Forecast Database (NDFD) provides access to gridded forecast of sensible weather elements. These sensible weather elements include: temperature, dew point, winds, chance of precipitation, precipitation amount, weather, and sky cover. These are plotted every ... 3 hours out to 72 hours; every 6 hours out to 168 hours. Additional variables include: max/min temperatures (every 24 hours, out to 168 hours), probability of precipitation (every 12 hours, out to 168 hours), precipitation amount (every 6 hours out to 72 hours), snow amount (every 6 hours out to 48 hours), and wave height (every 12 hours out to 120 hours). All of these parameters are available for time scales as small as an hour and space scales of a few kilometers. The NDFD will also contain, in time, watch and warning information and weather elements from National Centers for Environmental Prediction (NCEP) centers such as marine and climate products. Digital forecast data are archived for all NWS Weather Forecast Offices (WFO's) and are mosaicked and available for access for the coterminous United States (CONUS), Alaska, Hawaii, and Guam, as well as 16 predefined subsectors covering the CONUS.
Purpose: To make a wide range of climatic data available to researchers and the public.

Quality ATTRIBUTE ACCURACY REPORT: Central Quality Control--When the forecast grids from the WFOs arrive at the NDFD central server, they are automatically checked by software for consistency at the boundaries. If a discontinuity greater than agreed upon thresholds is detected, the submitting WFOs are automatically notified of a potential problem. The WFOs have the opportunity to modify their submissions ... to make them more compatible with their surroundings. NCEP will also have the opportunity to view the mosaic and offer suggestions to the WFOs. As a last resort, a consensus forecast may be calculated at WFO boundaries.
LOGICAL CONSISTENCY REPORT: Unknown
COMPLETENESS REPORT: Completeness information not available.
PROCESS DESCRIPTION: The NDFD is derived from the formulations of digital forecasts at each WFO. Using the Interactive Forecast Preparation System (IFPS), the WFO digital forecasts are updated as the need arises; they become official at a designated "effective" time when entered into the NDFD. The NDFD will be updated hourly, however this does not mean that all forecasts in the NDFD will be updated hourly, but usually only a small portion affecting limited area and/or periods.
