The dataset is designed for spatial comparison of monthly compound environmental pressure patterns. The compound-risk index should be interpreted together with the joint heat-ozone intensity and the carbon background layer. The four-class map identifies where elevated joint heat-ozone exposure coincides with elevated carbon background, rather than treating heat, ozone, and carbon as three independent event layers.
