LESO-CN&EU&US-O3-DAILY/MONTHLY/YEARLY

Hourly to yearly surface ozone (O3) concentration in China (mainland), Europe, and the United States on a 0.1 deg scale. The date range is from 2012 to 2021. This is the product of the LESO framework. The algorithm publications are 'Learning Surface Ozone From Satellite Columns (LESO): A Regional Daily Estimation Framework for Surface Ozone Monitoring in China' and 'Satellite-derived estimates of surface ozone by LESO: Extended application and performance evaluation'.本数据集涵盖中国（大陆）、欧洲及美国的地表臭氧（O3，surface ozone）浓度数据，时空尺度覆盖逐小时至逐年，空间分辨率为0.1度经纬度格网。 数据集的时间范围为2012年至2021年。 本数据集为LESO框架（LESO framework）的研发产物。 相关算法的发表文献分别为《基于卫星柱浓度数据学习地表臭氧（LESO）：面向中国地表臭氧监测的区域逐日估算框架》与《基于LESO的卫星反演地表臭氧估算：扩展应用与性能评估》。
