Monday gave us unexpectedly low PM2.5 levels, although we still had Unhealthy conditions for nearly the entire day. Tuesday looks to be very similar, so look for average or slightly better than average conditions for Beijing this time of year.
WEDNESDAY, February 19: The better-than-average conditions should continue through Wednesday morning, but it's likely that we will see the pollution accumulate again in the afternoon and evening.
THURSDAY, February 20: Look for another day of poor air quality on Thursday, with a good chance that we will see Very Unhealthy conditions at points throughout the day.
FRIDAY, February 21: More poor air quality is coming on Friday, again likely bringing us to Very Unhealthy conditions at points throughout the day.
