VAPOR conversion tools

Most likely, conversion of data from WRF-Fire can be achieved by a short script calling the following command line tools, supplied with VAPOR.

WRF to VAPOR

The wrfvdfcreate/wrf2vdf convert wrfout files to .vdf format. These are executables not scripts, and controlled by command-line arguments. The conversion should involve computing node height from the geopotential to node vertical cartesian coordinates (variable ELEVATION) and the interpolation from staggered wind mesh.

NetCDF to VAPOR

ncdf2vdf is a more general utility.

  • Is it possible to convert and use data at different resolutions (fire mesh, atmospheric mesh?
  • What about staggering of the wind mesh?
  • And conversion of geopotential to node height?
