Summer School on Atmospheric Composition and Dynamics
Reunion Island, 28 November – 3 December 2016
The Maïdo Observatory Summer School (MOSS) will focus on troposphere‐stratosphere composition and dynamics. The MOSS is intended to further develop understanding of monitoring techniques, processes and changes in the Earth’s atmosphere (troposphere and stratosphere) with emphasis on dynamics, long‐term evolution of atmospheric composition, and climate change. The academic activities will be based on courses and training in accordance with SPARC (Stratosphere‐ troposphere Processes And their Role in Climate) activities and with its strategy in terms of capacity development.
The School is scheduled for 6 days of coursework and is open to PhD students and early career researchers in the field of instrumentation and atmospheric sciences.
See the summer school website for further information:
