Variability and trends of water vapor in the Arctic (B05)

• Subject Area: Atmospheric Science
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 268020496

Water vapor is a strong greenhouse gas but how water vapor will change in the Arctic in future and how exactly it will influence the Arctic climate system is not well understood. We use ground-based reference water vapor observations from campaigns and permanent sites, as well as satellite observations, regional models and reanalyses to analyze the spatial and temporal variability of water vapor, its radiative effects, and long-term trends including their uncertainties.
