| ABSTRACT | We present a proposal to map vulnerability to extreme temperatures in the Metropolitan Area of Barcelona, departing from Local Climate Zones (LCZs). This classification allows working with a high spatial resolution (GSD<30 m). We derive the LCZs (Stewart and Oke, 2012), defined according to morphological, radiative and thermal parameters, from different maps representing land cover and land uses, 3D models of the city and remote sensors. Two new indexes are then proposed: the Urban Climate Vulnerability Index (UCVI) and Climate Vulnerable People (CVP). These two indexes, when combined, allow us to determine integrated vulnerability scenarios when considering situations of extreme temperature and heat waves in urban areas in order to have a detailed cartography of the risk. As an example of this, the proposed scenarios of vulnerability are coupled to a specific situation of the urban heat island registered by the high-resolution hyperspectral thermal sensor TASI carried out by the Institute Cartographic and Geological of Catalonia. Through comparing the different geospatial parameters, we are able to evaluate the potential risk due to the combination of vulnerability, hazard and exposure. This risk will increase in the future due to climate change and the rise of vulnerability. |
