Merge-Hydro Branch

This version will merge the version of ORCHIDEE developed at LMD with the 11-layer hydrological scheme into the latest version of the trunk (1.9.5.2). Based on the differences between the LMDZ version and those from which it originates (either 1_9 or 1_9_4_1) (see the attachments), several notes have been written in order to prepare the merge. Here below are the links to these notes.

The hydrology group is : isabelle.gouttevin,jpolcher,aducharne,aurelien.campoy,matthieu.guimberteau,gerhard.krinner,nathalie.de-noblet,catherine.ottle,pierre.brender.
Everybody with a svn login can(since 12 april 2012) download this branch but only people in the group can commit changes.

How to download ORCHIDEE Hydrology branch for use in offline configuration

1. Get modipsl

   > svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
   

2. Get the ORCHIDEE TOOLS-box. You will be prompted for username and password. Use personal svn login (firstname.lastname) or old sechiba cvs login.

   > cd modipsl/util
   > svn co svn://forge.ipsl.jussieu.fr/orchidee/trunk/TOOLS
   

3. Get the hydrology version. svn_login can be your personal svn login or sechiba

   > TOOLS/recup_my_ORCHIDEE svn_login branches/Hydrology
   

How to download ORCHIDEE Hydrology branch for use in coupled LMDZOR configuration

1. Get modipsl

   > svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
   

2. Modifiy in modipsl/util/mod.def to get ORCHIDEE Hydrology sources instead of default.

   In modipsl/util/mod.def change following line :
   #-C- LMDZOR_v4  ORCHIDEE                    orchidee_1_9_5   2  .   modeles
   into
   #-C- LMDZOR_v4  branches/Hydrology/ORHIDEE  HEAD             15  .  modeles
   

3. Compile

   cd modipsl/util
   ./ins_make
   cd ../config/LMDZOR_v4
   gmake
   

4. See wiki !LMDZOR_v4? for more information of using this configuration

Martial notes for the merge

Testing the Merge-Hydro version

Matthieu Guimberteau: Off-line tests in the Amazon with bug corrections

Aurélien Campoy (Feb 2012) - test peformed off-line using 50 years of SAFRAN met forcing for the SIRTA site, without routing, without STOMATE : compares reasonably well with the CWRR version of ORCHIDEE before the merge

Jan Polcher (March 2012) - Off-line simulation over Europe using the WATCH forcing data set : simulation performed, to be analyzed

Nicolas Vuichard (March 2012) - off-line tests at FLUXNET sites using STOMATE : ongoing

Fabienne Maignan (March 2012) - global off-line simulation

• forcings: ERA-Interim regular grid 0.72° 3-hourly/NCC 1° 6-hourly
• computer: LSCE/obelix*
• sequential or 4/8/16 procs
• sechiba only
• no routing
• segmentation fault SIGSEGV here:

   Projection arrays for Slope map                      : 
   nbvmax =           16
   We will work with      1000105  points of the fine grid
   Aggregate_2d : Slope map                     
   
   aggregate_2D nbvmax =           16 max used =           16
