Welcome to the users home page for the NCEP Unified Post Processing System (UPP). UPP was developed at the National Centers for Environmental Prediction (NCEP) and is used operationally for models maintained by NCEP, including the Global Forecast System (GFS), GFS Ensemble Forecast System (GEFS), North American Mesoscale (NAM), Rapid Refresh (RAP), High Resolution Rapid Refresh (HRRR), Short Range Ensemble Forecast (SREF), and Hurricane WRF (HWRF) applications. It is also used in the Unified Forecasting System (UFS), including the Rapid Refresh Forecast System (RRFS), Hurricane Application Forecasting System (HAFS), and the Medium Range Weather (MRW) and Short Range Weather (SRW) Applications. For more information regarding the UFS, please visit https://ufscommunity.org/.
The Developmental Testbed Center (DTC) provides assistance with facilitating research-to-operations (R2O) code development and community members are encouraged to provide new features to DTC for proposal into operational code.
At this time the DTC provides community support for UFS based forecasts. Support for WRF based applications has been retired, please see the archived UPP for WRF website for information.
