VPRM preprocessing for WRF-VPRM and STILT-VPRM modeling systems

Remarks:

  • There are two versions of the preprocessor available, one produces output which can be used with the WRF-VPRM system the other one for the STILT-VPRM system.
  • Both versions are in the same SVN repository organized in two branches. Updating one of the branches increases the revision number of the whole repository (both versions of the code, although maybe only one has been changed). Please check the changelog to keep track of the changes!
  • To use the Synmap by Jung et al. please download one of the R object files (".RData...") covering certain areas or the binary file ("synmap_LC_jan1") which has global coverage. Put either of these files in a directory of your choice which must be set in the "config.r" script in the variable "rdatain".
  • Further information can be found in the manual, which can be downloaded from this page.

STILT-VPRM

WRF-VPRM

Version of R46 to prevent memory buildup:

Excerpt from John Lin's email: "The reason to do this is that I was getting numerous places in the code in which the R jobs were crashing since they were not able to allocate enough memory along the way. I was running on an old Linux cluster with only 4 Gbytes of memory on each node, so it ran out of memory when dealing with huge arrays. The fix is to make use of the package "ff" in R, in which objects can be defined such that they are not loaded in memory, but stored on the hard drive. There are some subleties that I had to learn, but the "ff" package is really neat. Currently the low memory buildup option is implemented as the "ffTF" flag, specified within "config.r". Setting this to FALSE should make the code behave similarly as before the change."
