WPS Version 3.0

New features and bug fixes

• Support for IBM Blue Gene/L systems (Michalakes)
• Support for Mac Intel systems with g95
• Support for parallel compilation with MPI for g95 configurations
• Support for Linux systems with gfortran
• Greater flexibility in specifying geographical data set resolution to interpolate from; a sequence of resolutions to try can now be given for geog_data_res
• Update and correct several Vtables, add comments
• New support for JMA GSM and NCEP GFS Ensembles
• Fully support RUC hybrid grid files (thanks to Tanya Smirnova, ESSL/NOAA)
• Added an optional Product Definition Template column to the Grib2 Vtable. Now ungrib can distinguish between instantaneous (default) and accumulated fields (e.g. SNOWH).
• Added ability to decode tropopause and max wind levels from NCEP Grib files. (eventually these fields will be used in real.exe)
• Add ECMWF grid codes to g1print
• Improve appearance of plotfmt plots
• Metgrid will now halt if any fields contain points not covered by data
• Added utility program calc_ecmwf_p, allowing ECMWF model-level data to be better supported (Zaengl)
• The landmask field in geogrid can now be based off of data sets that have multiple water categories defining water regions
• Corrected serious error in rotation of ARW wind fields from non-earth-relative input wind fields that was present in v2.2.1 (although a bug fix was released for v2.2.1 immediately after the bug was discovered on 2007-12-05)
