The Environmental Modeling Center (EMC) is a premier developer of Numerical Weather Prediction systems. Our mission is to develop, enhance and maintain numerical forecast systems for the atmosphere, hydrosphere, and cryosphere in support of national and international forecast requirements. We accomplish this through close collaboration with an extensive network of partners from the academic, federal and commercial sectors. We are one of nine centers in the National Centers for Environmental Prediction (NCEP). NCEP, an arm of NOAA's National Weather Service (NWS), provides a wide variety of national and international weather guidance products to NWS field offices, government agencies, emergency managers, private sector meteorologists and oceanographers, and meteorological/oceanographic organizations and societies throughout the world. Together with the other centers in NCEP, EMC is a critical national resource in national and global weather prediction and is a starting point for nearly all weather forecasts in the United States.



Maintain, enhance and transition-to-operations numerical forecast systems for weather, ocean, climate, land surface and hydrology, hurricanes, and air quality for the Nation and the global community and for the protection of life and property and the enhancement of the economy.


With our partners, to be the world's best and most trusted provider of numerical forecast systems for weather, ocean, climate, land surface and hydrology, hurricanes and air quality.

  • Our Strategic Vision
    We maintain, enhance and transition to operations advanced numerical guidance systems for the Nation's weather/water/climate enterprise and the global community for the protection of life/property and the enhancement of the economy.
  • Our History
    EMC's history started with its predecessor, the Joint Numerical Weather Prediction (JNWPU) which began in 1954. Over the years EMC has evolved into one of the primary centers for the development and advancement in the nations' numerical weather, water, and climate prediction.
  • Collaborators
    Collaborating with other organizations is a crucial component to our success. We collectively improve our strength by collaborating with many government agencies, universities, private sector organizations, and interim projects within the NOAA community.
