no pollution spike yet - API of 17!

Sunset snapshot from a friend's window

The buzz among Beijingers (at least among my friends) today is how clean the air felt last night and today. And it turns out they're right. The API from noon yesterday to noon today was a lung-clearing 17. This is tied for the lowest on record (going back to June, 2000).

There have been only four days in the last eight years with an API of 17. They were 10/12/2003, 10/1/2004, and 8/15/2008, which I blogged about.

Update 10/20/08: In reviewing data today on MEP's new air pollution database website, I unexpectedly discovered the unbelievably low API of 12 listed for 9/23/08. That day currently ranks as the lowest API going back to June, 2000.

The pollution spike I feared occurring after 9/20 hasn't happened yet anyway...

The implication being that the temporary air quality measures had no effect whatsoever?

Just a freak year with lots of rain?
