NOAA Environmental Modeling System/NMMB Model (NEMS/NMMB)

NOAA Environmental Modeling Center/NMMB Model (NEMS/NMMB)

For the past several years, a common modeling framework called the NOAA Environmental Modeling System (NEMS) has been in development to streamline the interaction of analysis, forecast, and post-processing systems within NCEP. The NEMS architecture is based on the Earth System Modeling Framework (ESMF). This marks the first general use of ESMF within NCEP.

NEMS is a shared, portable, high performance software superstructure and infrastructure for use in operational prediction models at the National Centers for Environmental Prediction (NCEP). It is also part of the National Unified Operational Predication Capability (NUOPC) with Navy and the Air Force, and will eventually provide support to the community through the Developmental Test Center (DTC). Currently, the Global Forecast System (GFS), the Global Ensemble Forecast System (GEFS), the B-grid version of the Nonhydrostatic Multiscale Model (NMM-B), and the Flow-following finite-volume Icosahedral Model (FIM) are placed together within NEMS.
