Superparameterization of OpenIFS with DALES

sp-coupler is python code to couple different atmospheric models, namely the ECMWF OpenIFS global weather model and DALES, a small-scale atmospheric LES. In particular, sp-coupler aims at attaching an LES instances at a selected set of gridpoints of OpenIFS to establish a regional superparametrization of the global model. In such a setup, the two models run in a leap-frog cadence where the DALES models are forced by OpenIFS and produce turbulence, convection and cloud process tendencies for this GCM. The python scripts use the OMUSE framework to control DALES and OpenIFS and exchange the coupling data.
