WRF-NMM was developed by the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP). The NOAA/NCEP and the Developmental Testbed Center (DTC) are currently maintaining and supporting the WRF-NMM portion of the overall WRF code (Version 2) that includes:

• Nonhydrostatic Mesoscale Model (NMM) dynamic solver, including one-way static nesting;
• WRF Preprocessing System (WPS) / Standard Initialization (SI) package;
• Numerous physics packages contributed by WRF partners and the research community;
• WRF Postprocessing (WPP) package and scripts for several graphical packages.
  

NOMADS maintains the NAM in the 12-km 218 grid.
