National Digital Forecast Database

What is NDFD?

The National Digital Forecast Database (NDFD) is a suite of gridded forecasts of sensible weather elements (e.g., cloud cover, maximum temperature). NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP) are combined in the NDFD to create a seamless mosaic of digital forecasts. MDL contributed to the development of the NDFD and its companion project, the National Digital Guidance Database (NDGD). An overview of the project and its methods can be found in a 2003 article by Glahn and Ruth.
