New developments in SURFEX V8.1.0

This version contains the following novelties:

• 1) Optimization and MPI parallelisation of the PGD and PREP steps.
• 2) The general OPEN-MP in the OFFLINE driver is removed.
• 3) By default, the output written fields are all 1D-fields (there is no longer the dimension PATCH in output files).
• 4) The types introduced in version 8_0 are used to simplify the writing of several subroutines of the code.
• 5) Some obsolete options are suppressed.
• 6) The modifications of P. Marguinaud for the parallelization of the PREP with FULLPOS in AROME.
• 7) The modifications of J. Escobar and M. Moge for the MPI parallelization of the PREP_REAL, PREP_NEST_PGD and SPAWNING.
• 8) The parallel I/O server XIOS implemented in Surfex by S. Senesi.
• 9) The fortran interface for NETCDF4 replaces the previous NETCDF3 interface.
• 10) A first draft of the new coding related to the further building of ECOCLIMAP-SG.
• 11) The GRIB-API library is updated to version 1.17.0.
• 12) The output SNOW fields can be written 2D (number of points / number of snow layers), by M. Lafaysse (CEN).
• 13) The NETCDF forcing file can be partially read, by M. Lafaysse (CEN).
• 14) The definition of the OFFLIN output fields to be written is suppressed from files init_outfn_... .
• 15) The OFFLIN output fields are adapted to plot their fields with EPyGrAM.
• 16) The possibility to give CONDSAT, MPOTSAT, BCOEF, WWILT, WFC and WSAT, by soil layer, in the namelist NAM_DATA_ISBA, is added.
• 17) A correction for the forcing radiation is introduced, under key (C. Szczypta, P. Le Moigne).
• 18) Technical news for the assimilation part SODA (C. Albergel, S. Munier).
• 19) The XRD and DR_HOOK library are merged and updated to version 44.
