Various studies analysing and planning energy systems, grids, renewable energy plants, operation management strategies and energy markets require data from weather models as an input to carry out simulations. The input data to these simulations and its accuracy therefore have a significant influence on study results, subsequent recommendations, measures and development paths of the energy system. In practice, different studies often rely on different weather models and post-processing methods of the data provided by the weather models. This means that the comparability of different energy system modelling studies is often limited and it is often difficult to compare, interpret and contrast their results in a meaningful and transparent way. In addition, various studies have shown that the weather model data, which are used today, still have significant weaknesses from the user's point of view.

The overall objective of the project Medaillon is to create a new, user-friendly, open, high-quality and high-resolution meteorological data set for Germany. Moreover, the project aims to establish the data set as the standard meteorological data set used for system analysis and other applications in the energy system in Germany.
