NetCDFPlayer Model

The NetCDFPlayerModel can read a (specifically organized) netCDF file and write variables inside this netCDF to attributes in an entity group. The netCDF file must adhere to the following specification:

• There must be a time variable with a number of timestamps. The timestamps represent the number of seconds sinces t=0

• There must be at least one other variable which has the length of time as the first dimension and the length of the number of (target) entities as the second dimension

• the variable data must be either 32 bit or 64 bit floating points

After initialization the NetCDFPlayerModel reads the netCDF data and writes the source variable data per timestamp on the target attribute. The variable data is assigned to the target attribute on an “index” basis, not on an “id” basis.

Example Configuration

{
  "name": "my_player",
  "type": "netcdf_player",
  "netcdf_tape": "some_netcdf_tape",
  "entity_group": ["target_dataset", "target_entities"],
  "attributes": [
    {
      "source": "source_var",
      "target": "target.attribute"
    }
  ]
}
