This activity will provide an inventory of scaling methods of models used in the different Themes. For this purpose, crop, farm and economic models used in MACSUR and beyond will be screened for data types and data scales. The flexibility, rules and restrictions when dealing with data at different scales will be reported along with the applicability and actual use of scaling methods. In order to establish a basis for the comparison of scaling methods across varying model types, suitable common parameters of model-scaling method combinations will be identified. These are intended to serve as indicators for characterizing the model and data scale set-up. In addition, possible metrics for evaluating scaling methods across model types will be screened and rated qualitatively based on simulation experiments and literature.
