This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.

Abstract:

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.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
