Carsten Hoyer –Klick studied Physics at Oldenburg University in Germany and graduated from there in 1998 with a thesis on modelling solar thermal power plants. He then started working in the energy meteorology group of Oldenburg University with a focus on proving solar radiation data from satellite images for monitoring applications. In 2003 he changed to the German Aerospace Centre (DLR) into the Systems Analysis and Technology Assessment Group to build up the long term archive SOLEMI (Solar Energy Mining) of satellite based solar radiation data. His main field of research is solar resource assessment on the global level and is involved in various multilateral collaborations (e.g. UNEP-Solar and Wind Energy Resource Assessment (SWERA) Programme, IEA SHC Task 36 - Solar Resource Management). He is the coordinator of the European project MESoR (Management and Exploitation of Solar Resource Knowledge) bringing together all main European actors in the field of solar resource assessments.
