Abstract: Effective support for deep-fire missions requires a more accurate knowledge of atmospheric conditions than is presently available, especially for longer ranges. One key capability already in use by several NATO countries is the gridded meteorological (MET) message (METGM). The METGM consists of numerical weather prediction (NWP) output data that are presented in a standard format. The 3-D METGM (4-D if more than one forecast time) provides better MET information than the older 1-D computer MET message (METCM). Countries that adopted the METGM can convert NWP output into a METGM, but software developed for specific systems may not be readily available. Furthermore, development of conversion software has centered on European models and NWP formats used for models from major centers. There is no widely available capability to convert mesoscale model data using the Network Common Data Form format. This report presents a means to convert Weather Research and Forecasting model output in NetCDF format into a METGM. The METGM output of the current report is suitable for computation of firing solutions, but may not have all the optional output necessary for additional applications.
