Identifying the Change in Heat Vulnerability and Land-use Influence

Project Description

Extreme heat and cold are among the leading causes of climate vulnerability in the United States due to potential impacts on human health and well-being. In particular, residents in Connecticut are less acclimatized to the heat, which could signify a higher risk for heat-related diseases during extreme weather events. The occurrence of heat islands due to urbanization produces relatively warmer air temperatures near the ground, which makes urban and sub-urban areas warmer in comparison to rural areas. This project aims to identify variations in air and surface temperature over time and their linkages to land cover and land-use changes. The outcomes of this project are critical to support local decision-makers in determining the thermal vulnerability of local communities in the Resilient Connecticut project. The project will encompass the state of Connecticut with an emphasis in New Haven and Fairfield County areas. 

Project Timeline: May 2019 - June 2021

Project Outcomes

The main objective of this study will be to map and identify vulnerable areas to heat and cold, extreme climate conditions and identify the contribution of the changes in heat to vulnerability. The data will be used to model the differences between street and satellite measured temperatures and heat vulnerability in the area.  The technical report and maps will be posted to this site as they become available.
