Alternative formulation of cloud droplet activation

[oyvindseland]

What is the feature/what would you like to discuss?

New activation parameterisation from Athanasios Nenes in the Forces project. Exists in the Forces version of NorESM2 but should be reformulated. Expected to become default in NorESM2.5 Changed file: ndrop.F90 New files Ndparam.f and parametr.inc

Is there anyone in particular you want to be part of this conversation?

@ing

Will this change (regression test) answers?

Yes

Will you be implementing this enhancement yourself?

Yes
