Satellite Remote Sensing for Urban Heat Islands

The rapid growth of urban populations, the urban heat island (UHI) effect, and a potential increase in the frequency and duration of heat waves due to climate change, raise a series of issues about the increased health risks of sensitive urban populations to extreme heat and the effective means of mitigating impacts of heat waves. According to the US EPA, urban heat islands affect energy consumption, elevate greenhouse gas emissions, and impair water quality by increasing the temperature of urban water runoff. This will be ARSET’s first training on UHI and will be in collaboration with the National Integrated Heat Health Information System (NIHHIS) and the Global Heat Health Information Network (GHHIN).

This training will address the use of remote sensing in determining where “hot spots” of land surface temperature are located in urban areas, why these areas are experiencing increased temperature, which populations are most vulnerable, and ways to mitigate the effects through adaptive land use planning.
