This major release of the WRF Preprocessing System includes the following
notable changes and fixes:

  • A new command-line option to the configure script, --build-grib2-libs, will
    instruct the compile process to build internal copies of the zlib, libpng, and
    JasPer libraries, which will be installed in the WPS/grib2 directory. When
    --build-grib2-libs is provided as an argument to the configure script, the
    environment variables JASPERLIB and JASPERINC are ignored, and the compiled
    ungrib and g2print executables will always use the internally built GRIB2
    libraries.

  • A new bathymetry field (BATHYMETRY) has been added to the GEOGRID.TBL.ARW for
    use in the shallow water drag module in the revised M-O surface layer scheme
    for over-water roughness calculation.

  • A new tile drainage map (TD_FRACTION) has been added to the
    GEOGRID.TBL.ARW.noahmp to support the Noah-MP tile drainage scheme with a 30-
    arc-second CONUS tile drainage map.

  • The METGRID.TBL file has been updated to support the current Thompson AA
    microphysics scheme.

  • Since their processing can be expensive, the interpolation of subgrid
    variables can now be selectively enabled for specific domains (rather than
    processing them for every domain) by setting subgrid_ratio_x and
    subgrid_ratio_y larger than 0 on domains where subgrid variables are to be
    interpolated.

  • For subgrid variables, shift errors of about 0.375dx and 0.375dy (where dx
    and dy are the atmospheric grid spacing) have been corrected.

  • When processing terrain data for the WRF-Fire subgrid, the terrain gradient
    variables dzdxf and dzdyf are computed using the meteorological grid cell
    spacing from the outermost domain, thus resulting in an underestimation in
    gradient magnitude when max_dom>1 or the subgrid_ratio for the fire mesh is
    greater than 1. These errors have been corrected by accounting for the current
    domain resolution and the subgrid_ratio when computing the terrain gradient
    variables.
