Calculation for Climate Extremes (Posted 8/6/2014)
Problem: In V3.6, the statistics for climate extremes (option output_diagnostics = 1) will not be correct for a nested run.
Solution: Fix will be in V3.6.1 release.
Lake Physics (Posted 6/6/2014)
Problem: In V3.6, the lake physics option only works for a single domain.
Solution: Nesting is currently being worked on, and will be available in 3.6.1.
Bug Fix for Option fractional_seaice with sf_sfclay_physics = 1 (Posted 6/2/2014)
Problem: In V3.6, the surface layer physics option 1 is renamed from option 11 (revised scheme) from previous versions of WRF code, where fractional_seaice option wasn't available. When this option was renamed to 1 in V3.6, and fractional_seaice option was added, but an error is introduced. When fractional_seaice option is turned on, the surface layer physics used underneath is the old version. Thanks to Charles Seman of NOAA/OAR for pointing this out.
Solution: Download the fixed surface_driver file in the phys/ directory, and rename it to module_surface_driver.F. Recompile.
Option cu_rad_feedback (Posted 5/7/2014)
Problem: In V3.6 this option (which lets the radiation see the sub-grid cloud produced by some cumulus schemes) is not activated. This affects the Grell schemes (Grell 3, Grell-Freitas, and Grell-Devenyi) and the Kain-Fristch (KF) scheme (if the KF scheme is used with the "cu_rad_feedback" option activated).
Solution:Download the fixed routine to WRFV3/phys/ directory, and rename it to module_physics_init.F. Recompile.
Bug Fix for SBM Scheme (Posted 5/7/2014)
Problem: Three variables were left out in the SBM registry file in the released code. The full-version of the SBM scheme will not work with this bug.
Solution: Download the fixed registry file to the WRFV3/Registry/ directory, and rename it to registry.sbm. Do 'clean -a', and recompile.
Another bug fix is for the fast-version of the scheme. Download the fixed file here, rename it in the phys/ to module_mp_fast_sbm.F. (posted 5/9/2014)
Bug Fix for Option swint_opt (Posted 5/9/2014)
Problem: An error is introduced in 3.6 for this option (which interpolates shortwave solar radiation to each time step at the non-radiation steps). When this option is turned on, both SWDOWN and GSW (net) should be affected, but GSW was left out. This affects SLAB, RUC, PX and CLM as well as topo_shade, and sst_skin options.
Solution: Download the fixed radiation driver file in the phys/ directory, and rename it to module_radiation_driver.F. Recompile.
Configure File for Some OS Using PGI Compiler (Posted 5/9/2014)
Problem: With some mpich installations, using the PGI compiler still requires mpif90 -f90=pgf90. We have added additional options to accommodate it.
Solution: Download the fixed configure_new.defaults file to the arch/ directory.
Option to Download All of Above Changes: (Updated 6/2/2014)
Download this tar file in the WRFV3/ directory, untar it, and you should have all the files in their correct directories (no renaming is needed).
Restart issues
Problem: Tests revealed that the following options do not produce correct restart results: TEMF, Thompson aerosol-aware (mp_physics=28), Kain-Fritsch and Grell-type schemes with cu_rad_feedback on and global runs.
Solution: Work will be underway to fix these.
MAC Mavericks OS:
Problem: Current WRF/WPS code doesn't support CLANG, the default c compiler on this Mac OS.
Solution: Work is underway to resolve this issue. In the meantime, one can install gcc instead.
