Διερεύνηση βιοκλιματικών συνθηκών περιοχών του λεκανοπεδίου της Αττικής με σύγχρονες μεθόδους ανάλυσης και επεξεργασίας

Abstract

This paper investigated the conditions of thermal sensation in humans in areas of Attica with the use of remote sensing. Specifically made a comparative study of thermometers conditions, locations identified within the Municipalities of Athens, Penteli, New Smyrni and Elliniko using meteorological instruments were installed in those with satellite images obtained by satellite Landsat-5 TM. Two images were created by software model, a thermal image, which illustrates the spatial distribution of temperature and a vegetation index image. While the temperature was measured by organic soils and compared with the spatial distribution of temperature through the thermal image. Also, unless the temperature was recorded and the humidity, then calculated the thermohygrometric index THI, used to determine the thermal sensation.The comparison of the thermal image, the image of vegetation index showed that the presence of green spaces, contribute positively to the improvement of the thermal conditions of the urban environment. The higher values of THI were seen in places with dense structure, which is attributed to the nature of construction materials. Contrary to the positions involved in plant material observed improved conditions of thermal sensation
