Medium Range Forecast (MRF) and Nested Grid Model (NGM)
Entry ID: gov.noaa.ncdc.C00413

Abstract: The Nested Grid Model (NGM) and Medium Range Forecast (MRF) Archive is historical digital data set DSI-6140, archived at the NOAA National Centers for Environmental Information (NCEI). The National Centers for Environmental Prediction (NCEP) of the National Weather Service (NWS) runs a series of computer analyses and forecasts operationally, which use or produce model data. This data set is one of ... View entire text

Purpose: The analyzed data should provide a better representation of the real atmosphere than observations alone because of limitations in the observations. Some of these limitations are due to measurement error or other instrument problems, and nonuniform spatial and temporal distributions of the observations. At NOAA's Air Resources Laboratory (ARL), the NCEP model data are used for air quality transport and dispersion modeling.
