UPP User Release Version 4.0

Also see 'Known Issues' in this release, which is updated as needed.

Major Improvements and New Features include:

• Support for FV3GFS model output in NEMSIO format
  • Updated User Guide documentation to include information on post-processing the FV3GFS model output.
  • New output control files to produce fields from FV3GFS model output.
  • Logic to the run_unipost, run_unipostandgrads, and run_unipostandgempak scripts for reading and processing FV3GFS model output in NEMSIO format.

• Removal of build dependency on the WRF code package.
  • There is no longer a requirement to build WRF prior to building UPP; therefore, you’ll no longer receive a prompt for the location of a WRF build when compiling the UPP.
• Upgrade of the Community Radiative Transfer Model (CRTM) to V2.2.3.
  • Users should expect UPP synthetic satellite product results to change slightly due to minor changes in source code and coefficient files.
• Deprecated support for WRF-NMM binary model output and NEMS-NMMB model output. 
  • The routines for reading these model outputs have been removed and/or are no longer maintained. 

Additional release notes:

• Continued support for processing WRF-ARW model output in NetCDF format.
• Bug fixes applied as necessary.  
• Documentation updated (including the UPP users website, online tutorial and Users Guide).
• The release has been synced with the operational UPP version v8.0.0 at NCEP.
• A Docker container has been made available with limited functionality.
