      abstract     = {Interactions between the land surface and the atmosphere
                      play a fundamental role in the weather and climate system
                      through their influence on the energy and water cycles. Here
                      we present results of summertime land-atmosphere coupling
                      strength in a subset of the ERA-Interim driven EURO-CORDEX
                      model ensemble (1989-2008) including an evaluation of the
                      coupling related variables soil moisture and surface energy
                      fluxes of latent heat (LE) and sensible heat (H). Most of
                      the regional climate models (RCMs) reproduce soil moisture
                      and surface fluxes for the different European climate zones
                      reasonably well. However, for some regions and models
                      differences are identified, also compared to FLUXNET surface
                      flux measurements used as observational reference. To
                      quantify the coupling strength the H-LE-correlation method
                      has been confirmed as useful and valid for the comparison of
                      different RCMs. An important advantage of the method is that
                      it can be applied to standard RCM output variables (H, LE)
                      as well as to observations, although long time series of
                      high quality flux measurement data are needed, which are
                      available only for a few locations across Europe. For the
                      full 20-year period of summer seasons the EURO-CORDEX
                      simulations agree in the large-scale patterns, with strong
                      coupling in Southern Europe and weak coupling for Northern
                      Europe, also in agreement with the FLUXNET observations. For
                      large parts of Central Europe, however, the model ensemble
                      diverges between strong and weak coupling strength. Compared
                      to the FLUXNET measurements more models tend to overestimate
                      than underestimate the coupling strength. Higher model
                      resolution leads to more small-scale heterogeneity but not
                      necessarily to a change in the large-scale patterns.
                      Diversity in the ensemble can be both explained by the
                      different characteristics of the individual land surface
                      models (LSMs) as well as different climate conditions in the
                      models.},
