PM2.5 Forecast for Beijing - Thursday, July 18, 2013
Thursday will leave behind the two days of good air we just experienced in Beijing. We should see rising PM2.5 levels after midnight, and those increases should continue until about noon. By then, we should have moved through Unhealthy and up into Very Unhealthy. There is a good chance that we will see PM2.5 levels decreasing in the afternoon, until early evening when they should begin moving back up.
