Successful PhD defense by Ashique Vellalassery
On Friday, November 22, Ashique Vellalassery, PhD student at the IAP, successfully defended his dissertation entitled “Long-term trends and solar cycle response of Noctilucent Clouds” at the University of Rostock.
The thesis investigated the highest clouds in the Earth's atmosphere - noctilucent clouds (NLCs) - as indicators of atmospheric background conditions. The focus was on the influence of the 11-year solar cycle and the effects of increasing greenhouse gas concentrations on NLCs, water vapor and temperatures over 170 years. A key finding is the altitude-dependent response of water vapor to the solar cycle in the presence of NLCs, which becomes more pronounced after 1960.
Congratulations on this success!
The Leibniz-Institute of Atmospheric Physics is one of the German main centers for Middle Atmosphere research and maintains active cooperations with several international research organizations. The institute is located near the Baltic Sea resort Kühlungsborn, owns a separate site on the island Rügen, and is a major partner of the ALOMAR observatory in northern Norway. As associated institute of the Rostock University it is part of the teaching programme in physics. A total of about 90 persons is employed at IAP. The institute realizes an equal-opportunity and family-friendly human resource policy and is certified with the audit "berufundfamilie" ('career and family').
