Download GEFS Reforecast v2 Ensemble Data

This web page allows users to download model output from the 2nd-generation NOAA Global Ensemble Forecast System Reforecast (GEFS/R). The format of data downloaded from this page is netCDF-4 format. This page will will allow you to download one variable at a time. Please note that the more data you request, the slower your response time. Requesting many members and many months/years of data may take several hours to days to process. Please submit only one request at a time. If you wish to access the GRIB2 data, it is available via FTP at ftp://ftp.cdc.noaa.gov/Projects/Reforecast2 . Please see the README file for more information on the GEFS Reforecast v2 Ensemble Data and download information. If you encounter problems downloading data, please contact esrl.psd.reforecast2@noaa.gov .
