HeatShield

How can extreme heat risk be quantified at neighborhood scale by integrating climate, environmental, and demographic data to identify communities facing compounded vulnerability?

HeatShield develops a data-driven framework for mapping extreme heat risk at fine spatial resolution.

Inputs: Integrates temperature, air quality, wildfire smoke exposure, land-use characteristics, and census-derived demographics
Method: Combines climate observations with population data to model compounded environmental and social vulnerability
Key output: Identifies “double-burden” communities where exposure and sensitivity overlap
Application: Risk maps support targeted mitigation, policy analysis, and equitable decision-making under worsening heat extremes
