      abstract     = {Droughts have become more frequent and severe in Europe
                      over the last decade - a trend expected to continue. Recent
                      studies have shown widespread responses of energy, water,
                      and carbon fluxes in ecosystems to single drought years from
                      flux observations. However, to better understand how
                      ecosystems react to droughts, we need to gain explicit
                      knowledge about the different factors that influence their
                      response. In this light, it is crucial to associate the
                      influence of droughts on diverse ecosystem types with
                      particular compartments of the hydrological cycle
                      (atmosphere, surface, soil, and groundwater reservoirs). For
                      instance, during a drought, atmospheric dryness might be the
                      dominant factor in arid regions as opposed to dry soils in
                      humid regions.Here, we use states and fluxes of water and
                      carbon (vapor pressure deficit, surface runoff, soil
                      moisture, and water table depth) from the Community Land
                      Model 5 in a 3 km resolution over Europe from 1995 to 2018
                      to determine the drought anomalies of ecosystem processes
                      (gross primary production and evapotranspiration).
                      Importantly, we apply a systematic drought concept
                      integrating lags between deficits in a network of multiple
                      sections of the hydrological cycle during a drought.Our
                      analyses indicate that the dominance of a particular water
                      resource in controlling ecosystem processes converges
                      regionally and is predominantly consistent across drought
                      events. This finding emphasizes using more comprehensive
                      drought indices incorporating time lags and multiple water
                      resources when analyzing ecosystem responses. Lastly, it
                      identifies areas potentially threatened by droughts and
                      their controlling water resource.},
