Versions

2.2.0 - 10/11/2020

  • Summary of changes:

    • 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

2.0.0 - 01/02/2019

  • Changes relative to version 1.0.0:

    • 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).

    • 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 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.

    • 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.

1.0.0 - 01/06/2018

  • Changes relative to version 0.0.0:

    • MOZART-MOSAIC 4 bin, with aqueous chemistry and VBS SOA (chem_opt = 202).

      • Does not work with WRF-Chem version 3.7.1.
    • Morrison microphysics (mp_physics = 10).

    • Initial and boundary conditions for meteorology from ECMWF.
