Recent Upgrades to WRF Standard Initialization
• Most of the software is very similar to the original v1.0 release (ie., directory setup, installation procedure, and running still the same).
• Added interpolation to support mass coordinate (v_interp.exe)
• Added Arakawa-A (now supports both A and C grids) (gridgen_model.exe)
• SI supports inputs for LSM frozen soil physics.
• Added RUC grib as background/initialization (grib_prep.exe)
• Released better (“more automated”) localization procedure (perl scripts).
• Current tar is WRFSI.TAR.gz wrfsi_20020328.tar.gz which has the mass coordinate interpolation and.
WRFSI Upgrades (Cont)
• Developed domain relocalization GUI– Domain configuration
– Edits wrfsi.nl “hgridspec” section
WRFSI Upgrades (Cont)
• Program gridgen_model now includes:• “new” greenness fraction (0.144 deg resolution);• albedo climatology (from NCEP, 0.144 deg res);• New algorithm for processing albedo, greenness
fraction, and soil temperature data tiles: > Smaller (raw) tiles are grouped into a super tile
allowing horizontal interpolation methods to be applied, particularly for fields that require land-water mask.

NOTES
• More at WRF tutorial on Thur 6-27-02 2pm: “How to set up and run WRF SI”
• Latest software has not yet been posted to ftp site although the software is ready for “alpha” testing.
• Terrain, land-use, and soil-type are still processed by the same method as in the original release.- aggregation, averaging, dominant category.
• Still have as a goal to publish the WRFSI.
Potential Future Work
• Nesting • Improve Auto Configure for multiplatform builds• Parallelization• Further Design/Develop the GUI
– Build/Install WRFSI– FTP geography data (tar files)– Submit jobs to cron– What got in (to the analyses)– Configure other fortran namelist
