POST-PROCESSING
ARWpost
The ARWpost package reads in WRF-ARW model data and creates output in either
GrADS or Vis5D format.
The converter can read in WPS geogrid and metgrid data, and WRF-ARW input and
output files.
The package makes use of the WRF IO API. The netCDF format has been tested
extensively. GRIB1 format has been tested, but not as extensively. BINARY data cannot
be read at the moment.
Necessary software
GrADS software - you can download and install GrADS from
http://grads/iges.org/grads. The GrADS software is not needed to compile and run
ARWpost.
Vis5D software (http://www.ssec.wisc.edu/~billh/vis5d.html)
Vis5D libraries must be installed to compile and run the ARWpost code, when creating
Vis5D input data. If Vis5D files are not being created, these libraries are NOT needed to
compile and run ARWpost.
Obtain the ARWpost TAR file from the WRF Download page
(http://www.mmm.ucar.edu/wrf/users/download/get_source.html)
WRFV3 must be installed and available somewhere, as ARWpost makes use of the
common IO API libraries from WRFV3.
Unzip and untar the ARWpost tar file.
The tar file contains the following directories and files:
• README, a text file containing basic information on running ARWpost.
• arch/, directory containing configure and compilation control.
• clean, a script to clean compiled code.
• compile, a script to compile the code.
• configure, a script to configure the compilation for your system.
• namelist.ARWpost, namelist to control the running of the code.
• src/, directory containing all source code.
• scripts/, directory containing some grads sample scripts.
