Low or poor heat mitigation means that it is harder to cool the area. For example, asphalt roads, dark-colored roofs, and dense buildings are not able to mitigate heat very well, so those surfaces remain hot for longer. In contrast, high or good heat mitigation means that it is easier to cool the area. For example, parks, light-colored roofs, and natural open spaces are able to mitgate heat very well, so those areas become cooler more quickly. This map layer, created by NASA Develop, uses the INVEST model to analyse this heat mitigation index or cooling capacity. Darker colors indicate higher (better) cooling capacity. This layer helps to explain certain factors in urban heat island formation in the county, and can help with identification of strategies to mitigate heat. </SPAN></SPAN></P></DIV></DIV></DIV>
