                 systems are increasingly used to investigate
                 interactions between the system components. Due to the
                 different spatial and temporal scales of relevant
                 processes and computational restrictions, the
                 atmospheric model generally has a lower spatial
                 resolution than the land surface and subsurface models.
                 We employ multi-objective Genetic Programming (MOGP)
                 using the Strength Pareto Evolutionary Algorithm (SPEA)
                 to bridge this scale gap. We generate high-resolution
                 atmospheric fields using the coarse atmospheric model
                 output and high-resolution land surface information
                 (e.g., topography) as predictors. High-resolution
                 atmospheric simulations serve as reference. It is
                 impossible to perfectly reconstruct the reference
                 fields with the available information. Thus, we
                 simultaneously optimize the root mean square error
                 (RMSE) and two objective functions quantifying spatial
                 variability. Minimization solely with respect to the
                 RMSE provides too smooth high-resolution fields.
                 Additional objectives help to recover spatial
                 variability. We apply MOGP to the downscaling of 10 m
                 temperature. Our approach reproduces a larger part of
                 the variability and is applicable for a wider range of
                 weather conditions than a linear regression based
                 downscaling. Original publication: T. Zerenner, V.
