end of the games

First of all, apologies for the lack of posting this week; I've been busy watching as many events as I can while simultaneously struggling through a wicked cold. With the end of the Games finally upon us, though, I thought I'd fire off some quick numbers on how Beijing did:

First of all, Beijing met its goal of keeping the API below 100 during the Games. Here is the data for the 17 days 8/8/08-8/24/08:

Second, it seems the temporary policies (+ regular rains throughout the Games) worked; let's take a look at some average numbers for comparison:

Average Beijing API during the Olympics, 8/8/08-8/24/08: 49
Average Beijing API since the car ban went into effect, 7/20/08-8/24/08: 64
2007 Yearly Average Beijing API: 101
Average Beijing API during Olympic period 2007, 8/8/07-8/24/07: 86
Average Beijing API during Olympic period 2006, 8/8/06-8/24/06: 76

The average API in Beijing during the 2008 Olympics was 43% lower than the average API in Beijing during the same period in 2007. I'd say that's a pretty dramatic improvement.

More analysis to come.

There are ten days that API is below to 50.
