It is a set of scripts that allows a light automatic setup of LMDZ long chained climate simulations, including the installation of the model itself.
LMDZ_Setup can only be used on the Jean-Zay computer at Idris so far.
Coming VERY soon (summer 2024) : extension to other computing centers ("spirit", adastra) and Linux PCs

(Text extracted from LMDZ_Setup/README0_HowTo):
LMDZ_Setup consists in running LMDZ coupled to Orchidee for land surface (optional), but with imposed sea surface temperature.
The basic default configuration makes use of the IPSL-CM6A grid configuration and tuning, and runs a multi annual simulation on "climatological" amip sea surface temperature (with a mean annual cycle) using a calendar with 360 days.
Optionally : the configuration includes the ability to use interannually varying SST and to activate "nudging" by a reanalysis. In both cases, the calendar is then a real one. When nudging is activated, the simulation must be run on a monthly basis, while otherwise, it can be either monthly or yearly.
Since LMDZ_Setup automatically generates its own initial files, it can be run with zoom configurations by only changing the number of grid points ("resol" in main.sh) and the DEF/gcm.def file (see bellow).
Aerosols can be read for the year 2000 (weighted average over 1999-2001 cf Lurton et al 2020), and instantaneous forcing with respect to 1850 can be computed as well.
LMDZ_Setup can also run LMDZ coupled with the SPLA model (SimPLe Aerosol, activated with option aerosols=spla in setup.sh). Emissions of dust and sea salt are then computed interactively. For the time being, SPLA-specific input files (anthropic aerosol emissions)are only available on the grid zoomed over N Africa used by J. Escribano in his PhD thesis, and by B. Diallo and H. Senghor in subsequent work on N-African dust (file DEF/gcm.def_zNAfrica_BiJe).
A configuration with isotopes is also available since 2023-04.
