Assessing Spatial and Temporal Patterns of Observed Ground-level Ozone in China

Abstract Elevated ground-level ozone (O3), which is an important aspect of air quality related to public health, has been causing increasing concern. This study investigated the spatiotemporal distribution of ground-level O3 concentrations in China using a dataset from the Chinese national air quali...
