OASIS3-MCT Coupled applications using the Python interface pyOASIS

  • INRIA (FR): coupling between high-resolution CROCO ocean model and trained IA model for downscaling ERA5 atmospheric fluxes
  • BSC (ES): 2 python codes to create the remapping weights using OASIS auxiliary files (,,, uses hybrid MPI/OpenMP parallelisation, developed by Rodrigo Martín Posada.
  • EC-Earth4 (BSC), Forcing-reader :  Uses pyOASIS to implement a small Python component that reads forcing data from NetCDF files and sends via OASIS3-MCT coupling to, the atmosphere model (OpenIFS). At the moment still experimental. Developed mainly by Etienne Tourigny at BSC.
  • EC-Earth (U Lundt), LPJ-GUESS : Dynamic vegetation model developed at Lund University, coupled in  EC-Earth. Uses a C++ OASIS interface developed ~10 years ago using an “extern C” interface in the LPJ-G code and then Fortran name mangling by the compiler to call the actual OASIS routines. Not delivered with OASIS3-MCT sources, originally developed by Guy Schurgers and Uwe Fladrich.
