China Smog Alerts

China Smog Alerts

Visitors wearing masks to protect themselves from pollutants leave the Forbidden City on a heavily polluted day in Beijing Tuesday, Dec. 8, 2015. Beijing's red alerts for smog are as much about duration as they are about severity of pollution forecasts. The forecasting model must predict three or more days of smog with levels of 300 or higher on the city's air quality index - which typically would include having levels of dangerous PM 2.5 particles of about 10 times the safe level.
