International Autumn School "NEROGRAV"

The International Autumn School "NEROGRAV" will take place 5-9 October 2020 in Bad Neuenahr (near Bonn), Germany. The school is organized by the Research Unit NEROGRAV (New Refined Observations of Climate Change from Spaceborne Gravity Missions) which is funded by the German Research Foundation (DFG). It will educate a group of 35 Ph.D. students and junior scientists in state of the art satellite gravimetry data processing and applications of mass transport data in Earth system sciences related with the global water cycle, the oceans, the cryosphere or the atmosphere.

Participation Fee will be 295 EUR, all details incl. flyer are available at There are some vacant places. Please register as soon as possible not to miss the school!
