Historical Unidata Internet Data Distribution (IDD) Gridded Model Data

Historical Unidata Internet Data Distribution (IDD) Gridded Model Data are obtained via the Unidata Internet Data Distribution System (IDD). Data includes gridded analyses and forecasts from US National Centers for Environmental Prediction (NCEP) and European Centre for Medium-Range Weather Forecasts (ECMWF) models. Models include NCEP ETA, NAM and RUC covering the Continental US, NCEP Ensemble and GFS covering North America and the globe, and GFS Extended and ECMWF covering the globe, at various spatial and temporal resolutions. Potential variables found in the model output include pressure, relative humidity, temperature, geopotential height, zonal component wind speed, and V-component wind speed.
