Abstract Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate interactions in rapidly changing Arctic, uncertainties their prediction persist. Here, we harmonize SEB observations across a network vegetated and glaciated sites at circumpolar scale (1994–2021). Our variance-partitioning analysis identifies vegetation type as an important predictor SEB-components during Arctic summer (June-August), compared to other SEB-drivers including climate, latitude...
Universities and other institutions are currently faced with the goal of utilizing responsible practices regarding carbon dioxide (CO2) emissions. At University Zurich, initiative to start real-world laboratories inspired innovations science-based studies explore additional options for mitigating CO2 emissions from operations through both direct indirect vegetation processes, i.e. sequestration reduction in reduced energy consumption buildings due shading cooling effect trees, respectively....
The Arctic is experiencing amplified climate warming, decreasing sea ice extent, increasingly earlier springtime snowmelt, and a related increase in fire activity. transition from cold to warm season the strongly varies between years, but our understanding of temperature surface energy budget changes over limited. Here we investigate intraseasonal variability components their interannual trends 40 years (1981–2020) across terrestrial (above 60° N) using ERA5-Land reanalysis data. We found...
<p>The terrestrial Arctic is subject to extreme climatic changes including increases in temperature and precipitation patterns. At the heart of these developments lie land surface energy budget (SEB), which couples important earth system processes carbon water cycles. However, despite importance SEB, uncertainties predictions high-latitude SEBs persist, specifically for SEB-components sensible latent heat fluxes.</p><p>These have part been attributed...
The majority of climate models predict severe increases in future temperature and precipitation the Arctic. Increases can lead to an intensification hydrologic cycle that strongly impacts Arctic environmental conditions. In order investigate effects scenarios on ecosystems, manipulation experiments are being performed simulate drought extreme However, most existing research so far has been unevenly distributed, primarily focusing temperate grasslands woodlands. Despite large changes...
