The separate components each define their own config files, but can import certain variables from a central config file in the parent directory.

Following standard Netcdf conventions the coordinate variables have the same name as the dimensions. These variables have long names, types, and units that conform as much as possible to standard CF conventions. The Ascii file generated by Flexpart (raw_tr_file ) is split according to releases and converted into a CSV format that is better suited to Metview.

Adding an Ncdrd file to a mosaic dataset in Linux with a Python script fails, and returns the error, "Error: 80042098: Unable to recognize the specified file as Ncdrd." Some packages, such as TUWmodel and topmodel, allow a spatial distribution of the hydrological processes. TUWmodel, for instance, allows the user to implement a semi-distributed application with differentiation into elevation zones, while …

These numerical modelling products cover all seas around the globe, from the surface to the seabed, at horizontal resolutions of between 1/36° and 1°, depending on the geographical area.
