PM2.5 Forecast for Beijing - Thursday, September 26, 2013
The good air quality from the first of this week keeps hanging around, much longer than the extended forecasts would have had us believe a day or two ago. As a result, we could still see Good or Moderate air quality on Thursday morning and possibly even Thursday afternoon. The general trend of PM2.5 levels should be moving up, potentially giving us Unhealthy air as early as noon, although that is not the most likely outcome. The most likely trend would see us moving into Unhealthy for Sensitive Groups at or shortly after noon, then moving into Unhealthy after sunset.
