Implemented new functionality for downscaling in coupler ‘OASIS3’ (Shrestha et al. 2011). Can be used as DOWNSCAL option in the OASIS3 configuration file. The downscaling algorithm is based on the work of Schomburg et al. (2010).
In spite of the integration of OASIS3 into the repository, it still needs a few other libraries to run.

For more details on OASIS3: https://verc.enes.org/oasis

This algorithm, downscale, is built to work with COSMO (Consortium for Small-scale Modelling) data. It will be able to force CLM, the community land model, in the future. At the moment, it is run in a dummy setup. Model1 substitutes the coarse-scale model, while it actually does little more than read coarse-scale files, and model2 stands in for the fine-scale model. It reads one fine-scale variable, the geometric height of the surface, as a predictor and writes out the downscaled variables. OASIS3 orchestrates the exchange of variable fields.
