Arctic Land Surface Energy Fluxes and their Impact on the Earth System under Current and Future Conditions
Session ID#: 78307
Session Description:
Climate over Arctic land warmed considerably by up to 5°C in the last century and a substantial increase in temperature and precipitation is projected for the 21st century. These changes indicate alterations in Arctic land surface energy fluxes. However, despite their importance, the Arctic land surface energy budget and its components have received relatively little attention in the past. This session aims to improve the current understanding of the Arctic surface energy budget and its relevance for the Earth System. We invite researchers to present theoretical, observational, empirical and modeling studies on Arctic surface energy fluxes and the energy budget and interactions with processes such as carbon and water cycling, permafrost thaw and biodiversity change. We invite researches of all relevant disciplines (e.g. remote-sensing, climatology, ecology) and scales (local, pan-arctic, global) to present their findings, data and/or methods.
