UPP Users Page

Welcome

Welcome to the users home page for the NCEP Unified Post Processing System (UPP). UPP was deleveloped at the National Centers for Environmental Prediction (NCEP) and is used operationally for models maintained by NCEP. The NCEP Unified Post Processor has replaced the WRF Post Processor (WPP). The UPP software package is based on WPP but has enhanced capabilities to post-process output from a variety of NWP models, including WRF-NMM, WRF-ARW, Non-hydrostatic Multi-scale Model on the B grid (NMMB), Global Forest System (GFS), and Climate Forecast System (CFS).

The Developmental Testbed Center (DTC) maintains a community version of the UPP code that aligns with what is used operationally at NCEP. Features and developements from NCEP are continually brought back into the community UPP package and likewise community members are encouraged to provide new features to DTC for proposal into operational code.

At this time the DTC provides community support for WRF based forecasts (ARW/NMM) and NEMS-NMMB forecasts.

UPP V3.1 was released September 28, 2016
