PM2.5 Forecast for Beijing - Thursday, May 23, 2013
Thursday's graph should look familiar by now; it's the same pattern we've seen several times over the last couple of weeks. After starting out at Unhealthy for Sensitive Groups , we should climb up into Unhealthy and possibly Very Unhealthy before PM2.5 levels begin to drop around late morning or noon. Late afternoon and early evening should give us the best air quality of the day, even giving us a chance at Moderate quality for a while.
