Testing the refactored net and CAM variable transformations

Closed this issue · 1 comments

Some suggestions from Paul regarding testing the refactored parameterisation back in SAM, and also checking the variable transformations implemented as part of porting to CAM:

  • Implement the new parameterization with CAM type inputs (qv, qcc, qii, tabs) in SAM and see that it gives similar results to the original implementation.
  • Implement the new parameterization in SAM (as above) but now running SAM with a slightly different vertical grid z and/or a longer time step. This would test the interpolation and subcycling. Note the time step can't be much longer or SAM will go unstable.

Consider working on these once this phase of the project is underway.

This is tested by passing an input forwards and then backwards through the two conversions.

We test:

  • Dry air
  • Unsaturated moist air
