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.
