This is the version 3.9 release of the WRF code. The release includes all components of the system:

  • WRF model (including ARW and NMM/HWRF)
  • WRF-Chem
  • WRFDA

WPS and WRFPLUS have also been updated, but these codes are kept separately from this repository. Click those respective links for further details.

The highlights of the new release are:

WRF ARW model:

  • Hybrid sigma-pressure vertical coordinate as an alternative vertical coordinate
  • P3 microphysics
  • Stochastically perturbed parameter scheme and stochastically perturbed physics tendencies
  • Improvement to RAP/HRRR physics and various other physics
  • Runtime performance improvement through optimization of advection routines

See http://www2.mmm.ucar.edu/wrf/users/wrfv3.9/updates-3.9.html for full details

WRFDA:

  • New assimilation capability: 4DEnVar
  • Cloudy radiance assimilation capability for AMSR2
  • Radar "null-echo" assimilation

See http://www2.mmm.ucar.edu/wrf/users/wrfda/updates-3.9.html for more information

WRF-Chem:

  • TUV photolysis option
  • Coupled WSM6 microphysics with MOZART gas wet scavenging
  • Modified GOCART dust scheme for the SORGAM and MOSAIC chemistry options
  • A new trajectory option that calculates meteorological and chemical properties
    along air trajectories

WRF-NMM-HWRF:

  • The 2016 operational update, which includes surface layer and ocean coupling updates; the GFS EDMF PBL scheme, and a scale aware SAS cumulus scheme.
