COSP diagnotics in NorESM3

[Ovewh]

I have done some Nudged simulations (2019-2020) with high frequency cosp output. LINK to ADF comparing a model to model run. I could not find obs to compare against, if someone know where the obs are, then it would be straightforward to do model to obs comparison.

To enable COSP:./xmlchange CAM_CONFIG_OPTS="-phys cam7 -camnor -cosp -chem trop_mam_oslo -model_top lt"

There is a few caveats: (1) The COSP output needs to be on SE-grid. (2) ADF do not support SE timeseries creation, thus you need to create the timeseries separately. But you can plot timeseries files directly in ADF.
