      Diekmann, Christopher J.ORCIDiD; Schneider, MatthiasORCIDiD; Knippertz, PeterORCIDiD; de Vries, Andries J.ORCIDiD; Pfahl, StephanORCIDiD; Aemisegger, FranziskaORCIDiD; Dahinden, FabienneORCIDiD; Ertl, BenjaminORCIDiD; Khosrawi, FarahnazORCIDiD; Wernli, HeiniORCIDiD; Braesicke, PeterORCIDiD (Journal of Geophysical Research: Atmospheres, 2021-10-05)
      We present a Lagrangian framework for identifying mechanisms that control the isotopic composition of mid‐tropospheric water vapor in the Sahel region during the West African Monsoon 2016. In this region mixing between ...

      Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8 kilometers altitude, ozone was on average 7% ...
