ORCHIDEE

This manual provides the information about the land-surface model ORCHIDEE (technical page for advanced users) from Institute Pierre Simone Laplace (IPSL). Its installation on the HPC of the CIMA called hydra.

Model description

• ORCHIDEE: sechiba & stomate
• Two major modes of simulations: Off-line (no feedback) / on-line (LMDZ, WRF)

All forcing data to run ORCHIDEE is located here in CIMA's HPC:

${ORforcing}=/share/DATA/ORCHIDEE/IGCM/

Off-line atmospheric forcings

Desdcribed here: ORforcings

Atmoshperic variables required by ORCHIDEE: LWdown, PSurf, Qair, Rainf, SWdown, Snowf, Tair, Wind_E, Wind_N

Available data-bases in hydra:

• WFDE5 CRU GPCC (v1, 0.5°): mixing ERA5 CRU and GPCC: WFDE5_CRU_GPCC_[YYYY].nc at hydra:

${ORforcing}/METEO/WFDE5_CRU_GPCC/v1/

Morphological forcings as data-base

Installed in CIMA's HPC hydra at

/share/DATA/ORCHIDEE/IGCM/SRF

To be interpolated to the domain of simulation (region and resolution) at the first time step (done by ORCHIDEE) Mandatory:

PFT map

15 PFT, percentage of each by grid-point (maxvegetfrac, see table for equivalencies of PFT)

PFTmap_IPCC_[YYYY].nc (0.5°, basic), a file per/year ESA-LUH2, v2 at:

${ORforcing}/PFTMAPS/CMIP6/ESA-LUH2v2/historical/15PFT.v2/PFTmap_2000.nc

carteveg5km.nc (Olson's global classification of 94 PFT, 5km transformation)

No temporal evolution at:

${ORforcing}/PFTMAPS/

Global Olson vegetation at 5 km of resolution Homolosine projection

Soil characterisitcs

• soilcolor used to define background-albedo: albedowet, albedodry (using values from 1 to 8). To be find in soils_param.nc, soils_param_zobler.nc
• soiltexture to define soil type, to be grouped as 3 types: corse, medium, fine (from 7 values). 3 different sources:
• soils_param.nc (1.°, basic)
• soils_param_zobler.nc: 7 types (1°)
• soils_param_usda.nc: 12 types (0.08331404°)

WOODHARVEST

SOIL_BULK

Additional

• LAI: on runs without stomate (otherwise, LAI is dynamic), one needs to provide climatologies of the LAI: 13 LAI values which evolves along time (monthly climatology) lai2D_[00/01/03].nc
• Albedo: on runs without stomate (otherwise, albedo is dynamic) new maps only for the bare soil albedo at higher resolution to avoid the use of soilcolor from soils_param.nc. Fixed values for wet/dry background albedo. Or a new file
  • alb_bg_jrctip.nc: albedos climatologies retrieved from MODIS satellite JRC-TIP package
  • alb_bg_modisopt_2D.nc: Another non.climatological albedo from MODIS

${ORforcing}/albedo

• Routing: routing.nc: worldwide data-base of river basins at 0.5°: 1-8 direction, <89 point at the sea, ... (trip), riverID (basins), water retention (topoind), etc..., cartepente2d_15min.nc topography slope (0.25°)
• Floodplains: floodplain.nc To account for maximum flooded area: lake, dam, swamp, saline, pond, irrig
• Chemistry: orchidee_fertilizer_1995.nc with fertilization (for N₂) for rice and the others
• Reference Temperature: To be used as a reference temperature for the soil (reftemp.nc)

All ORCHIDEE configuration is controlled by run.def.: Domain, period, physics activation, sechiba/stomate, routing, floodplains, ... ORparameters

I/O controlled by *.xml files from XIOS libraries

• iodef.xml: main XIOS configuration
• context_orchidee.xml: I/O global configuration for ORCHIDEE
• field_def_orchidee.xml: definition of I/O variables (names, units, dimensions, long-name, ...)
• file_def_orchidee.xml: definition of variables at each file (output frequency, level of output, ...)

Installation

This installation guide is based on the installation in different machines from CIMA/DCAO computational resources:

• CIMA's HPC ORcompHYDRA hydra
• DCAO's computational classroom ORcompDCAO DCAO

which it must have pre-installed: netCDF libraries (netcdf-dev, netcdff), MPI libraries (mpi, mpich), Fortan and C compilers (gcc, gcc++ gfortran), pre-processing tools (cpp), subversion repository code tool (svn), Makefile (make, gmake), shells (ksh, csh)

NOTE

Each new version of the code, has its own XIOS files! Make sure that you're using the right ones!! (otherwise, you would have an error...)

Running the model

ORCHIDEE can run in a large variety of forms. Here is desribed a simple way to run a year of simulation using the off-line configuration and the trunk branch.

Assuming a working directory ${WORKDIR} (e.g.: /home/lluis.fita/estudios/SensLuLc_MarcosJuarez/trunk)

Linking atomspheric forcing files (0.5° WFDE5 CRU GPCC v1 files)

Getting the XIOS files (they might be version-dependant, therfore, it is recommended to get them directly from the same folder where the compiled version of ORCHIDEE is located, INSTALLDIR=/share/ORCHIDEE/)

$ cp $INSTALLDIR/modipsl/modeles/ORCHIDEE/src_xml/*xml ./

Edit the file_def_orchidee.xml to define output frequency and level of of output (remove all the _AUTO_)

$ vim file_def_orchidee.xml

The final configuration gets:

$ cat file_def_orchidee.xml | grep 'file id' 
 <file id="sechiba1" name="sechiba_history" output_level="11" output_freq="1D" enabled=".TRUE.">

Getting the PBS scheduling job to run ORCHIDEE

$ cp /share/ORCHIDEE/run_or.pbs ./

Launching the model

$ qsub run_or.pbs

If everything went fine, one should have (at least)

orout/sechiba_history.nc  orout/sechiba_history_4dim.nc  stomate_history.nc

• sechiba_history.nc, sechiba_history_4dim.nc, stomate_history.nc: Outputs (optional, only when stomate is activated)
• sechiba_rest_out.nc, stomate_restart.nc: restarts for sechiba<code> and <code>stomate (optional, only when stomate is activated)
• out_orchidee_[nnnn]: standard output files for each process
• river_desc.nc: output with river description (optional, only when routing is activated)

Running the model in DCAO's computational lab

OR4L: L. Fita's work-flow management for ORCHIDEE

ORCHIDEE should be run with libIGCM which is a work-flow management for ORCHIDEE developed at the IPSL.

However, L. Fita developed an independent simpler and less potent work-flow called OR4L. See how it works in this wiki page ORCHIDEE/OR4L OR4L

OR_1proc: DCAO's 1-proc work-flow management for ORCHIDEE

DCAO's computational lab machines are 1 processors standard machines. A new work-flow management has been created for such cases. Mostly related to the UMI & DCAO course of [land-atmosphere interaction and its modelling]. All the iformation is available in the wiki page OR1proc OR 1proc
