Cím:	Simulation of the mean urban heat island using 2D surface parameters : empirical modeling, verification and extension / Balázs Bernadett, Unger János, Gál Tamás, Sümeghy Zoltán, Geiger János, Szegedi Sándor
Dátum:	2009
Megjegyzések:	The spatial distribution of the annual mean urban heat island (UHI) intensity was simulated applyingempirical models based on datasets from urban areas of Szeged and Debrecen, using simple and easily determinable urbansurface cover variables. These two cities are situated on the Alföld (Great Hungarian Plain) and have similar topographicand climatic conditions. Temperature field measurements were carried out, Landsat satellite images were evaluated, and thenone- and multiple variable models were constructed using linear regression techniques. The selected multiple-parametermodels were verified using independent datasets from three urban settlements. In order to obtain some impression of themean UHI patterns in other cities with no temperature measurements available, the better model was extended to urbanareas of four other cities situated in geographical environments similar to Szeged and Debrecen. The main shortcomingof typical empirical models, namely that they are often restricted to a specific location, is overcome by the obtainedmodel since it is not entirely site but more region specific, and valid in a large and densely populated area with severalsettlements.
