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.本数据集专为月度复合环境压力格局的空间对比分析而构建。复合风险指数（compound-risk index）需结合联合热臭氧强度与碳本底图层进行解读。 该四分类地图可识别出联合热臭氧暴露升高与碳本底升高相重合的区域，而非将热、臭氧与碳视作三个独立的事件图层进行单独分析。
