Extreme Heat Event and Health Risk (Canada)
Global climate change has increased intensities, frequencies and severities of heat waves in past decades. It created fatally heat waves in mid-latitude cities, such as 2003 heat waves in Paris and other European major cities, 2010 heat wave in Montreal, and 2009 heat wave in Vancouver. In order to reduce the fatal risks from heat waves and develop protocols for future health planning, this project uses Greater Vancouver Area (GVA) as a study site and creates high resolution air temperature maps for GVA with remote sensing applications. This map is used to analyze the correlation between temperature and heat-related mortality, as well as heat vulnerable population, socioeconomic factors and building structures/types. The goal of this research is to locate the potential hotspots in the city that may face higher fatal risks during heat waves, and to apply the heat risk map for emergency use and health planning in the future.
