Phys.org: Powerful new dataset reveals patterns of global ozone pollution. “Although ozone pollution is dropping across many parts of the United States, western Europe and Japan, many people living in those countries still experience more than a dozen days every year in which levels of the lung irritant exceed health-based standards. That’s one conclusion from a new health assessment based on the Tropospheric Ozone Assessment Report or TOAR, an effort by the International Global Atmospheric Chemistry Project to create the world’s most comprehensive database of surface ozone observations from all available ozone monitoring stations around the globe. The paper was published today in the journal Elementa: Science of the Anthropocene.”
