Abstract

Mediterranean is identified as one of the most vulnerable areas in the context of future climate projections and global warming. Greece in particular, has experienced significant warming over the past 3 decades, which is more pronounced in summer. At urban areas, air temperature trends are the result of the additive effect of global warming and urbanization. The study focuses on the city of Athens and aims to investigate and quantify the contribution of the urban effect to the recent significant warming, observed at the area. Although spatial distribution of urban heat island in Athens is extensively studied, its temporal variability hasn’t been investigated. Long term observations of surface air temperature at stations of different characteristics (urban, suburban, coastal, neighbor rural etc.) are analysed in order to estimate the evolution of urban heat island (UHI) intensity over time. Temporal variability of UHI at the different stations provides information on increasing/decreasing or stabilized urban effect and enables the estimation of the rates of background warming. Analysis is performed on an annual and seasonal basis.
