3.2. Recovering LTL forcings

In the new version of Osmose, only one format of input files can be used.

  • LTL variables should be on a regular grid

  • LTL variables should be 3D, with dimensions (time, y, x)

  • There is one variable per LTL species

  • The names should be consistent with the configuration files (plankton.name.plk# parameters)

It is the user who is in charge to interpolate the raw forcing files (provided by biogeochemical models) into the Osmose grid (cf. Section 3.1). The user has to consider whether data should be vertically and/or horizontally averaged or integrated.

The structure of a sample LTL forcing file is provided below:

netcdf corr_eco3m_gog44_conversion_factor {
dimensions:
    longitude = 40 ;
    latitude = 26 ;
    time = 240 ;
variables:
    double longitude(longitude) ;
    double latitude(latitude) ;
    int time(time) ;
    float CILC(time, latitude, longitude) ;
    float COPC(time, latitude, longitude) ;
    float HNFC(time, latitude, longitude) ;
    float PHYSN(time, latitude, longitude) ;
    float PHYLN(time, latitude, longitude) ;
}
