WPS Version 4.1
This release includes the following notable changes:
* The addition of support for a MODIS 15-arc-second land use dataset with lakes.
- This dataset is described in
Broxton, P. D., Zeng, X., Sulla-Menashe, D., & Troch, P. A. (2014). A global
land cover climatology using MODIS data. Journal of Applied Meteorology and
Climatology, 53(6), 1593-1605. DOI: 10.1175/JAMC-D-13-0270.1
and may be activated by prepending the geog_data_res namelist option with
'modis_15s_lake+' after downloading the dataset.
* The addition of initial support for POWER systems running Linux with the XL
compilers.
* Adjustments to the RH field from GEFS data to be w.r.t. liquid water, as is
done for GFS, CDAS, and ECMWF.
* A change in the default mean sea-level pressure field from smooth PRMSL to
unsmoothed MSLET for GFS datasets.
* Corrections to the rotation of horizontal wind vectors that are provided on
a Cassini/rotated lat-lon projection.
WPS Version 4.0.3 This minor release of the WPS fixes several small issues in the WPS code, and is expected to have no impact on model results. * The configure script is now capable of detecting a WRF build in ../WRF-4.0.3. * Compiler warnings about truncated strings when building the g1print utility with the GNU compilers have been addressed. * The non-standard "-f90=" and "-cc=" options to MPI compiler wrappers have been removed from several configuration stanzas. * An inconsequential bug in metgrid that led to the incorrect detection of geogrid v4.0.1 output as v4.0 output has been fixed.
WPS Version 4.0.2 This minor release of WPS, Version 4.0.2, updates the system to address two minor issues in the ungrib program. These were necessary to allow successful building and running on a Cray platform. * A Fortran continuation directive in subroutine rrpr was modified. * As Ungrib only uses unpacking and decoding functions, references to unused packing and encoding routines, whose unnecessary compilation would have required mods to enable on a Cray, were removed from the g2 subdirectory makefile.
WPS Version 4.0.1 This bug-fix release of the WPS addresses one significant issue in metgrid and several other minor clean-up items. * The metgrid program now supports the use of input meteorological datasets on a rotated latitude-longitude projection that provide a grid-relative horizontal wind field. In particular, this allows the WPS to properly use NCEP RAP data. * The default path of the static, geographical datasets has been updated to reflect re-organization of the NWSC /glade filesystem. This change should only benefit users of NWSC Cheyenne. * The logic in the configure.wps script has been updated to better locate new WRF source code that was obtained either by cloning the WRF GitHub repository or by downloading a GitHub archive file.
WRF Pre-processing System Version 4.0
This release includes the following notable changes:
* Introduction of a 'lowres' option for geog_data_res to select coarse resolution
(typically, 5-arc-minutes) sources for all mandatory static fields. This is
useful in educational contexts or when the size of the geographical datasets
must be minimized, e.g., when teaching with WRF/WPS in a Docker container or
in the cloud.
* New GEOGRID.TBL entry for a pre-computed urban fraction field (FRC_URB2D) based
on 30-meter NLCD 2011 data.
* A change in the default source of data for the MAXSNOALB and ALBEDO12M fields.
The new defaults are MODIS-based and higher resolution.
* Two fixes for numerical inaccuracies in the polar stereographic projection.
* A new namelist option for ungrib, pmin, to specify the minimum pressure to
extract from isobaric datasets.
* A combined Vtable for all CFSR/CFSv2 data, both pressure-level and surface
fields (Vtable.CFSR).
* Added support for NCAR RDA's ECMWF "ds113.1" dataset.
* Added support for FV3GFS GRIB data.
* Generally, in the v4.0 release of the WPS, there is a move towards a model
for handling geographical static fields in which all static fields that are
not required by the default WRF namelist are optional from the viewpoint of
geogrid.
- Datasets that were previously mandatory but that are now optional:
VAR_SSO and LAKE_DEPTH.
Note: There are now three types of downloads for the static, geographical data:
(1) Download the "full-resolution" sources for all default, mandatory fields.
Use this download for all simulations where accuracy is important.
(2) Download the "low-resolution" sources for all mandatory fields.
Use this download for testing and educational purposes.
(3) Downloads for individual, optional geographical fields.
Obtain these datasets as needed by different model options.
