| description | <p>Vegetation plays a vital role in the Earth system by
sequestering carbon, producing food and oxygen, and providing evaporative
cooling. Vegetation productivity extremes have multi-faceted implications,
for example on crop yields or the atmospheric CO<span class="inline-formula"><sub>2</sub></span> concentration. Here, we
focus on productivity extremes as possible impacts of coinciding,
potentially extreme hydrometeorological anomalies. Using monthly global
satellite-based Sun-induced chlorophyll fluorescence data as a proxy for
vegetation productivity from 2007–2015, we show that vegetation
productivity extremes are related to hydrometeorological hazards as
characterized through ERA5-Land reanalysis data in approximately 50 % of
our global study area. For the latter, we are considering sufficiently
vegetated and cloud-free regions, and we refer to hydrometeorological
hazards as water- or energy-related extremes inducing productivity extremes.
The relevance of the different hazard types varies in space;
temperature-related hazards dominate at higher latitudes with cold spells
contributing to productivity minima and heat waves supporting productivity
maxima, while water-related hazards are relevant in the (sub-)tropics with
droughts being associated with productivity minima and wet spells with the
maxima. Alongside single hazards compound events such as joint droughts
and heat waves or joint wet and cold spells also play a role, particularly in dry
and hot regions. Further, we detect regions where energy control transitions
to water control between maxima and minima of vegetation productivity.
Therefore, these areas represent hotspots of land–atmosphere coupling where
vegetation efficiently translates soil moisture dynamics into surface fluxes
such that the land affects near-surface weather. Overall, our results
contribute to pinpointing how potential future changes in temperature and
precipitation could propagate to shifting vegetation productivity extremes
and related ecosystem services.</p> |
