Priority cool roof opportunity index

Overview

This layer shows the priority cool roof opportunity index and can help answer the question: Where is it possible to increase surface reflectivity of a large area using cool roofs in places that also have high surface temperatures?

The index assigns equal weight to two components: hazard and opportunity. Hazard is assessed as land surface temperature. Opportunity is assessed as cool roof opportunity.

Function
To help answer the question: Where is it possible to increase surface reflectivity of a large area using cool roofs in places that also have high surface temperatures?

Cautions
Cool roof opporunity is estimated from satellite data albedo data which is affected by cloud cover, atmospheric conditions, and the angle and orientation of roofs.
