Versions#

2.3.0 - 04/02/2021#

Updates

  • Action needed:

    • Either clone the new repository.

    • Or add the following changes to an existing WRFotron:

      • In config.bash, add netcdf/4.6.3 to the loaded modules.

      • In namelist.wrf.blueprint, remove all instances of auxinput5/6 from the &time_control section.

        • This fixes meteorological spin up in CEMAC builds issue.

      • In namelist.chem.blueprint, change dust_opt to 13.

        • This replaces dust_opt 3 for WRFChem4.2 issue.

      • In pre.bash, remove duplicate WRF_UoM_EMIT/ in path for copying over the final_output (line 149).

  • No action needed:

    • CEMAC conda module includes python libraries required for post-processing (pp_concat_regrid.py) script.

    • CEMAC modulefile for WRFChem4.2 updated for build 2.

      • This fixes the N2O5 chemistry issue.

    • CEMAC build for WPSChem3.7.1 fixed for geogrid and metgrid.

    • Removed superfluous anthro_emis.inp from WRF_UoM_EIT.

2.2.0 - 10/11/2020#

Updates

  • Changing default settings to turn on heterogeneous uptake of N2O5 onto aerosol particles. Within namelist.chem.blueprint, n2o5_hetchem = 1.

  • Added introductory Python course for analysing WRFChem output.

  • Added blueprints for CEMAC/manual compilation runs.

  • Added Python postprocessing script.

  • Changed default cores to 64.

2.1.0 - 23/06/2020#

Updates

  • WRF-Chem4.2

    • Fixes the performance interval of WRFChem4.0.3 issue.

  • If still use WRFChem3.7.1, then add aqueous chemistry in stratocumulus clouds in WRFChem3.7.1 issue.

  • Refactored the GitHub repository:

    • Converted user guide to readthedocs.io documentation.

    • Focus on CEMAC WRFotron.

    • Removed old WRFotron code but kept a reference to the settings they used in the user guide.

    • Removed superfluous files.

  • Added no binding for MPI executions -bind-to none in main.bash and main_restart.bash.

  • Added NCO and chemistry variables list version checks to main.bash and main_restart.bash.

  • Changed the default memory per core to 2G for main.bash and main_restart.bash.

2.0.0 - 01/02/2019#

Updates

  • WRFChem4.0.3.

  • With aqueous chemistry in stratocumulus clouds (cldchem_onoff = 1).

    • Works with WRFChem4.0.3.

  • Biomass burning plume rise throughout the boundary layer (bbinjectscheme = 2).

    • The original option 2 was 50% at the surface and 50% evenly throughout the BL.

    • The new option 2 has all BB emissions evenly distributed throughout the BL.

    • To add the bbinjectscheme to any new version of WRFChem see here.

  • Diurnal cycle from Olivier et al., (2003).

  • Aerosol optical properties approximated by Maxwell-Garnett.

  • Updated TUV scheme for photolysis (phot_opt = 4).

    • Download the additional data files here to your WRFChem/run folder.

    • Extract the data directories DATAE1 and DATAJ1, and the wrf_tuv_xsqy.nc file from downloaded file using tar xvf TUV.phot.bz2.

  • Initial and boundary conditions for chemistry from WACCM for post 2018 or CAM-Chem for pre 2018 here.

  • Fixed the bug where nudging would stop after 312 hours (i.e. after day 13 of a simulation) i.e. changed gfdda_end_h to 10,000.

  • Nudge above the boundary layer. To do this, go into namelist.wrf.blueprint, and within the FDDA section change:

    if_no_pbl_nudging_uv                = 1, 1, 1,                                    ! nudging of u and v in the PBL, 0 = yes, 1 = no
if_no_pbl_nudging_t                 = 1, 1, 1,                                    ! nudging of t in the PBL, 0 = yes, 1 = no
if_no_pbl_nudging_q                 = 1, 1, 1,                                    ! nudging of q in the PBL, 0 = yes, 1 = no

  • Hard-coded NCL and NCO commands.

  • Fixed the bug where within the anthro_emiss namelist for EDGAR-HTAP2, NH3 was incorrectly set as an aerosol i.e. removed (a) in the emis_map.

  • Fixed the bug in plume rise where extra biomass burning mass was added aloft when the thickness of the vertical grid (dz) increases by altitude.

    • Within chem/module_chem_plumerise_scalar.F:

      • dz_flam=zzcon(k2)-zzcon(k1-1) ! original version.

      • dz_flam=zzcon(k2+1)-zzcon(k1)   ! fixed version.

  • Corrected the metInc within config.bash for ECMWF to be 6 (3 was for GFS).

  • Added the faster version of post.bash from Helen Burns in CEMAC.

    • Hard coded NCL and NCO commands in.

    • Also, removed the deletion of pre-processed and temporary wrfout files from the staging directory, as these are often needed for error diagnosis.
