UPP User Release Version 4.1.0

Release Date:

The UPP User Release Version 4.1.0 was released on March 31, 2020.

Release Notes

Major Improvements and New Features include:

  • GOES 16 products
  • Fields related to HRRR-smoke (e.g. smoke tracers, visibility, etc.)
  • FV3GFS model data in netcdf formal
  • Code access via GitHub repository 

New Directory Structure & Build Dependencies:

  • Removal of several supporting NCEP libraries from the UPP package and making them a pre-install library dependency
  • Removal of copygb code to its own individual repository to be installed and used as a separate utility (https://github.com/NCAR/copygb)
  • Reorganization of the directory tree to align with EMC code
  • New dependencies required to be pre-installed prior to building UPP code
    • NCAR/NCEPlibs (https://github.com/NCAR/NCEPlibs)
      • Note that this repository is seperate from the authoritative NOAA NCEPLibs repositories; it is maintained by DTC staff and may have minor code changes from that of NOAA maintained libraries.  This is necessary to ensure continued support for current features. Work is underway to transition to the authoritative NOAA repository in effort to remove this redundancy.

** Please carefully read the new procedures on the UPP Users webpage or in the V4.1 Users’ Guide for building the software. 

Additional release notes:

  • Serial builds are no longer supported.
  • This will be the last supported version for WRF model data.
  • This will be the last supported version of GRIB1 output format.


Known Issues and Fixes

The run_unipost and run_unipostandgempak scripts fail for FV3GFS runs

Posted: 2020-04-03
Problem: A bug in a couple of the provided sample run scripts was found that causes an error and the script to exit with a message about input format when trying to process FV3GFS data.  Using the scripts to process WRF model data is unaffected.  Only run_unipost and run_unipostandgempak scripts were impacted.  Another bug linking an existent error was also identified and fixed, though this should not have impacted users.
Solution: Updated sample run scripts are provided here.
