Summer drought weakens land surface cooling of tundra vegetation. Abstract (from manuscript): Siberia experienced a prolonged heat wave in the spring of 2020, resulting in extreme summer drought and major wildfires in the North Eastern Siberian lowland tundra. In the Arctic tundra, plants play a key role in regulating the summer land surface energy budget by contributing to land surface cooling through evapotranspiration. Yet we know little about how drought conditions impact plant-mediated land surface cooling by tundra plant communities, and related positive feedback to the high air temperatures. Here we used high-resolution land surface temperature and vegetation maps based on drone imagery to determine the impact of the extreme summer drought in 2020 on land surface cooling in the lowland tundra of North-Eastern Siberia. We found strong differences in land surface cooling among plant communities in the drought year 2020 and the reference year 2021. Further, we observed a decrease in the ... |
