ABSTRACT. - Analysis of Urban Local Climate Using In-Situ Measurements Concentrated human presence evidently modifies the natural environment. On local scale, one of the major effects is related to urban areas. Recently, we have started in-situ urban measuring program in a downtown district of the Hungarian capital. The study area within Budapest is located near the river Danube in the southern central part of the city, and mainly consists of 3- and 4-storey older and newly built buildings, which is a result of the local government concentrated efforts completing several block rehabilitation programs starting from 1980s. Since 1993 in the most densely built inner part of the district entire blocks were renovated and modified in order to create more liveable environment for the citizens. Within the framework of these programs, inner parts of the blocks were demolished, thus, inside the blocks more common green areas could be created. The resulting climatic effects are evaluated now on the basis of temperature and relative humidity measurements. Our main goal is to analyze whether the generally positive changes of the built environment can also be recognized in the urban heat island effect of the rehabilitation area.
