Set up a simulation with routage highres

Author: L. Rinchiuso

Routage highres is developped by Jan Polhcer. It is currently available in branch ORCHIDEE_2_2 since revision 7576.

Do as follow if running ORCHIDEE_2_2 offline

• Use an experiment with the new driver
• Use revision 7576 or more recent on branch ORCHIDEE_2_2. Compile as default.
• Create a routing_graph.nc file routing_graph.nc files with the codes hydrolinks/Point2Pixel ​https://gitlab.in2p3.fr/ipsl/lmd/intro/hydrofiles/-/tree/master/Point2Pixel and routingpp ​https://gitlab.in2p3.fr/ipsl/lmd/intro/routingpp (branch Hydrolinks) to be used instead of the stanfard routing.nc. To run this last code a grid of the atmospheric forcing is needed, if not available it can be created with this code ​https://gitlab.in2p3.fr/ipsl/lmd/intro/gengeogrid
  • To run with SAFRAN forcing you can use the routing_graph.nc here: /gpfsstore/rech/ngp/uzb75jm/Test_SAFRAN_hydrolinks_MERIT_nbasmax15_MaxDistErr5_MaxUpstErr20_graph_complete.nc (then a few examples of routing graph for different forcings will be added to the shared forcing file repositories). This routing graph file has been created with revision 8db844da of Point2Pixel and revision 38402872 of the branch Hydrolinks of routingpp

• In run.def set:

RIVER_ROUTING=y
ROUTING_METHOD = highres

• In COMP/sechiba.card in BoundaryFiles? set:

(/gpfswork/rech/ngp/uzb75jm/SAFRAN/SAFRAN_15nbasmax_20MaxUpstrErr_10MaxDistErr_MERIT_graph_topo.nc, routing_graph.nc), \

Note: when using SAFRAN (as for the example above) activate the GRID and follow the procedure for a regular_x_y grid, i.e.

• In run.def set:

GRID_FILE = grid.nc

• In COMP/orchideedriver.card in ListNonDel? set:

(/gpfsstore/rech/ngp/uzb75jm/geogrid_SAFRAN.nc, grid.nc)
