Software Release: Announcing UPP V9.0.0 Release

Dear UPP Community,

The Developmental Testbed Center (DTC) is pleased to announce the release of the Unified Post Processor Version 9.0.0. This release marks another major change in the UPP code base, by adding support for the newly released Short-Range Weather Application (the limited-area application of the Unified Forecast System) and discontinuing support for WRF and GRIB1 data. Users of UPP with WRF data should continue to use the UPP V4.1 release, as this most recent release does not support WRF output.

Users will note that the release version numbering has skipped ahead from 4 to 9; this is part of a larger unification effort with National Oceanic Atmospheric Administration (NOAA) operations, and the development of the Unified Forecast System. Please review the updates carefully.

The build procedure and software dependencies have been updated to fit within the UFS software framework. The motivation for these changes is to further align the community software with operational software, to help facilitate code management procedures. Changes include:

  • Use of CMake for building/installing
  • Build dependency on the official NCEPLIBS package ( rather than the NCAR fork
  • CRTM coefficient fix files are now packaged separate from the code base.

Please carefully read the new procedures on the UPP Users webpage or in the V9.0.0 Users’ Guide ( for building the software. 

Major Improvements and New Features include:

  • FV3 limited-area model (LAM) data is now supported (netCDF format only)
  • FV3GFS global model data now supports nemsio format in addition to netCDF
  • CRTM updated to v2.3.0
