Analysing dynamic parameters for urban heat stress incorporating the spatial distribution of urban structure types

Land-use and land-cover (LULC) and their changes have significant influence on heat balance, especially in the urban area. Therefore climate measurement stations are permanently set-up on different land uses, and additionally mobile climate measurements are carried out every year at the same time and similar climate conditions. The study area is Santiago de Chile, one of the most dynamic and fast growing cities in South America. Urban Structure Types (UST) are delineated for areas under investigation in which the urban morphology is rather characteristic for the social strata. UST are compared with climate parameters to find out if significant correlations exist between UST and climate measurements. The overall goal is to estimate environmental justice in large urban agglomerations.
