讲座简介：

Stratospheric water vapor (SWV) is an important greenhouse gas for the radiative budget and for understanding of stratospheric transport. Merged water vapor measurements and long-term simulations with chemical transport models (CTMs) driven by reanalyses are two widely-used means of reconstructing the long-term record of SWV over the past 3-4 decades. The natural variability of SWV entering the stratosphere spans a large range of time scales. We show preliminary results of SWV simulations for the period of 1980–2013 using the Chemical Lagrangian Model of Stratosphere (CLaMS) driven by three modern reanalysis products, which allow us to quantitively estimate uncertainties in modelled SWV related to the input reanalysis fields.

主讲人简介:

Dr. Mengchu Tao received her doctorate from Wuppertal University in Germany. She currently holds a postdoctoral appointment at Forschungszentrum Jülich, where her research is focused on using the CLaMS model to simulate and understand the mechanisms that control the chemical composition of the stratosphere. She has published eight papers on this topic in high-quality journals, including Atmospheric Chemistry and Physics, Geophysical Research Letters, Geoscientific Model Development, and the Journal of the Atmospheric Sciences.
