MIT researchers improve upon methods to model urban air pollution

Green Car Congress

Urban regions account for an ever increasing fraction of Earth’s population, and are consequently an ever increasing source of air pollutants. These pollutants include anthropogenic aerosols, which have important climate and health implications. Cohen and Prinn used meteorological and emissions data from 16 representative urban areas.

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. In some parts of Asia, Africa and South America, the researchers identified data gaps which prevented them from characterizing ozone pollution exposure patterns.
