The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was completed over the 36-year period of 1979 through 2014. The CFSR was designed and executed as a global, high resolution, coupled atmosphere-ocean-land surface-sea ice system to provide the best estimate of the state of these coupled domains over this period. The current CFSR will be extended as an operational, real time product into the future.

This website allows you to download daily CFSR data (precipitation, wind, relative humidity, and solar) in SWAT file format for a given location and time period. For more information about CFSR data, please visit our publications page.

Recently we have had a high volume of requests. We are working to upgrade this service as soon as possible. In the meantime, please give your request up to several hours to complete and do not re-submit the request--this will just backlog the requests further.

Step 1: Select your bounding box

Hold the Shift key and drag to select your bounding coordinates on the map. Or, type your latitude/longitude coordinates below. For quick response, bounding coordinates must not exceed 12 decimal degrees latitude and 12 longitude. You may submit a larger area, but it will be subject to approval by an administrator before running and make take several weeks to complete depending on the size and number of years requested.
