Contents
Post-processing tools provided with the Venus PCM
First and foremost there are a number of postprocessing utilities (self-standing tools) which can be found in the UTIL and LMDZ.VENUS/Tools directories. Secondly one has some extra main programs in the dynamics-physics interface.
UTIL
LMDZ.VENUS/Tools
Main programs (other than GCM) but included in the Venus PCM package
There are a few other main programs that are included with the GCM.
Advanced stuff: these main programs are located under LMDZ.VENUS/dynphy_lonlat/phyvenus/ as they are at the interface between lon-lat dynamics and the Venus physics package
start2archive
This program collects multiple start.nc and startfi.nc files from a series simulations and store them in a start_archive.nc file. For this one simply needs to run the startarchive program in the directory. It will automatically fetch start.nc and startfi.nc files and generate start_archive.nc. If a start_archive.nc file is already present then the current start.nc and startfi.nc files are added to the start_archive.nc file (which can contain multiple initial states, as long as they are on the same grid and correspond to different dates.
The startarchive program should be compiled at the same resolution as the gcm which produced the start files, using the makelmdz_fcm compilation script
newstart
This program is to:
- extract (and interpolate)
restart.ncandrestartfi.ncfiles from astart_archive.ncfile or from a pair ofstart.ncandstartfi.ncfiles. The subtle difference between the two setup is that grid interpolation (horizontal and/or vertical) is only possible if using astart_archive.ncinput file - modify values and fields contained in the initial condition file
- Compiling
newstartis done using the makelmdz_fcm utility. The program is then meant to be run interactively with the user providing options and choices when prompted. - Once the program has run and finished without error, it will generate
restart.ncandrestartfi.nc
The rcm1d 1D column program
The source code is located under LMDZ.VENUS/libf/phyvenus/dyn1d
