PM2.5 Forecast for Beijing – Wednesday, December 11, 2013

Wednesday's air quality forecast is a little strange because the weather forecasts we have are very inconsistent.  You can expect to see Good or Moderate air through the early morning hours, but we could see PM2.5 start to accumulate some around sunrise.  If that occurs, we should see the air quality deteriorate to Unhealthy for Sensitive Groups and possibly to Unhealthy during the afternoon.  But a different weather forecast predicts conditions that would keep us at Good or Moderate air quality through the morning and into the early afternoon, when we would see a small increase in pollution.  We think it is most likely that Wednesday's air quality will not be as good as Tuesday's, but it should still be better than average for Beijing.
