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 and wait for that to finish before submitting another. If you submit many requests, they will be queued up until your other requests are completed.

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 .
