PM2.5 Forecast for Beijing - Friday, September 27, 2013
It looks as if this run of great air has ended. Late Thursday evening, we are already on the upper end of the Unhealthy Range, and the increasing trend should continue overnight. It is likely that we will climb up into Very Unhealthy before the PM2.5 levels peak around 8AM. Then we should see some decreasing in pollution in the late morning and afternoon before levels begin to rise again after sunset.
