      abstract     = {The nationwide extent of surface ozone pollution in China
                      and its comparison to the global ozone distribution have not
                      been recognized because of the scarcity of Chinese
                      monitoring sites before 2012. Here we address this issue by
                      using the latest 5 year (2013-2017) surface ozone
                      measurements from the Chinese monitoring network, combined
                      with the recent Tropospheric Ozone Assessment Report (TOAR)
                      database for other industrialized regions such as Japan,
                      South Korea, Europe, and the United States (JKEU). We use
                      various human health and vegetation exposure metrics. We
                      find that although the median ozone values are comparable
                      between Chinese and JKEU cities, the magnitude and frequency
                      of high-ozone events are much larger in China. The national
                      warm-season (April September) fourth highest daily maximum 8
                      h average (4MDA8) ozone level (86.0 ppb) and the number of
                      days with MDA8 values of >70 ppb (NDGT70, 29.7 days) in
                      China are $6.3-30\%$ (range of regional mean differences)
                      and $93-575\%$ higher, respectively, than the JKEU regional
                      averages. Health exposure metrics such as warm-season mean
                      MDA8 and annual SOMO35 (sum of ozone means over 35 ppb) are
                      6.3-16 and $25-95\%$ higher in China, respectively. We also
                      find an increase in the surface ozone level over China in
                      2016 and 2017 relative to 2013 and 2014. Our results show
                      that on the regional scale the exposure of humans and
                      vegetation to ozone is greater in China than in other
                      developed regions of the world with comprehensive ozone
                      monitoring.},
