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.},
