Extending rojak

Other meteorological data sources

Loading data from a different meteorological data source (i.e. not ERA5 data) can be achieved by,

1. Adding a new class: To keep the package structure consistent, create a new module in rojak.datalib (e.g., rojak/datalib/ifs.py) and within that create a new class (e.g. IFSData)

2. Implementing the interface: Make the class subclass/implement rojak.core.data.MetData and satisfy any abstract methods or properties required by that interface.

3. Providing the adaptor: Implement the abstract method MetData.to_clear_air_turbulence_data() on the new class. This method must return a rojak.core.data.CATData instance.

4. Verifying compatibility: Add unit tests that confirm to_clear_air_turbulence_data() returns a valid CATData and that required fields are correctly mapped.

5. Using with diagnostics: Convert your MetData instance via to_clear_air_turbulence_data() and pass the returned CATData to rojak.turbulence.diagnostic.DiagnosticFactory to instantiate diagnostics.
