Tool Box Mars PCM

Post-processing tools provided with the Mars PCM

First and foremost there are a number of postprocessing utilities (self-standing tools) which can be found in the

LMDZ.MARS/util

directory; you certainly want to first read the README file there.

Current contents of this directory is:

aeroptical.def     extract.F90          lslin.def        startarchive2icosa/
aeroptical.F90     extract.points.def   lslin.F90        streamfunction.F90
aeropt_mod.F90     extract.profile.def  README           xvik/
compile            hrecast.def          simu_MCS.def     zrecast.auto.def
concatnc.def       hrecast.F90          simu_MCS.F90     zrecast.F90
concatnc.F90       localtime.def        solzenangle.def  zrecast.manual.def
expandstartfi.F90  localtime.F90        solzenangle.F90

the compile script is an example of how to compile any of the utilities, which you will have to adapt to your needs (mostly concerns setting the right path to the NetCDF library). All the post-processing tools are meant to be run interactively (asking the user for some instructions), hence the *.def files as it is most of the time more convenient (once one knows the tools and questions it will ask) to redirect this list of answers to the standard input of the tool, e.g.

zrecast.e < zrecast.manual.def

Main programs (other than GCM) but included in the Mars PCM package

There are a few other main programs that are included with the GCM

start2archive

A main program to collect multiple start.nc and startfi.nc files from a series simulations and store them in a start_archive.nc file.

newstart

A main program to:

• extract (and interpolate) restart.nc and restartfi.nc files from a start_archive.nc file
• modify values and fields contained in the initial condition file

Compiling newstart is done using the makelmdz_fcm utility

xvik

A post-processing utility to analyse the modeled CO2 cycle

Other

Mention here other pre or post processing utilities...
