Version 3.9 of the WRF Pre-Processing System (WPS) was released on 17 April 2017.

New features and Updates:

  • The default data source for the LANDUSEF/LU_INDEX fields have been updated in v3.9 for ARW:
  • LU_INDEX/LANDUSEF are now derived from a variant of the 20-class, 30-arc-second MODIS data with an algorithmically added lake category, which is different from the 21-class MODIS dataset available in v3.8 and earlier with lakes;
  • Soil fields SOILCTOP and SOILCBOT are now interpolated from 30-arc-second data, rather than 2-arc-minute data.

Geogrid:

  • Geogrid can now handle large (> 2GB) tiles of static data;
  • Logic to prevent accidental combination of land use datasets that use different classification schemes (Thanks to Brian Reen, US Army Research Lab);
  • Add capability to explicitly not use optional static datasets (Thanks to Brian Reen, US Army Research Lab);
  • Added GEOGRID.TBL.ARW.noamp specifically for use when creating domains for simulations in which a user will activate the crop or groundwater modules in the Noah-MP scheme.

Ungrib:

  • Added capability to vertically interpolate to new levels in isobaric datasets (Thanks to Brian Reen, US Army Research Lab);
  • introduce the capability to process rotated lat-lon RAP/HRRR data.

Metgrid:

  • WRF simulations can now be initialized from MPAS output via a new capability in the metgrid program to read and interpolate netCDF MPAS output on the native, unstructured MPAS mesh;
  • introduce the capability to process rotated lat-lon RAP/HRRR data.

New terrestrial data sets:

  • 30-arc-second, 16-category BNU soil category datasets, selectable by prefixing geog_data_res with 'bnu_soil_30s+'

Bug fixes:

  • Fixed a bug in computation of df/dx fields (Thanks to Branko Kosovic of NCAR).
  • The v3.8.1 bugfix for processing newer NCEP NAM data that use complex packing has been included in the v3.9 source.
