The Geography department is delighted to congratulate Simone Kotthaus on receiving the American Metrological Society/International Association for Urban Climate Student award for her ICUC8 2012 conference presentation 'Long-term flux observations in London: Energy, water and carbon dioxide exchange in a dense European city centre'.
In August 2012 the King's College London Urban Micrometeorology research group participated in the 8th International Conference on Urban Climate (ICUC8) in Dublin, Ireland. This five-day meeting, organized by the International Association for Urban Climate (IAUC) brought together specialists from all over the world to discuss the latest advancements in monitoring and modelling (micro-) meteorological processes in the urban environment. The King's research group contributed with presentations on various topics ranging from small scale data processing techniques over long-term local scale observations up to larger scale modelling approaches.
Kotthaus's presented results from measurements taken on rooftops of the King's and Strand buildings at the Strand campus of King's College London. The measurements were obtained using radiation sensors and eddy covariance systems which allow for the measurement of surface energy fluxes. The net all-wave radiation and the turbulent fluxes of heat and water vapour were important variables determining microclimate conditions which affect the thermal comfort of the city’s inhabitants. The results from these measurements in central London revealed a very strong impact of the dense urban surrounding on processes governing the surface energy exchange. This was expressed in high heat fluxes maintained by anthropogenic emissions, small evaporation fluxes due to the limited moisture availability and altered surface albedo in response to the heterogeneous surface structure made of modern construction materials .
