I’ve frequently mentioned the very useful US Embassy pollution monitor here in Beijing, which used to be only on Twitter but is now easier to access. First there was the non-blocked website, which I strongly recommend; now I’m happy to report that someone has designed an iPhone/iPod Touch app! Now it’ll be even easier for parents, teachers and anyone interested to follow the hourly updates. As I’ve mentioned often, this real-time data can give us fortunate Beijingers a lot of control in implementing pollution action plans, especially in schools.
I haven’t downloaded it yet, so please let me know if there are problems…

Or at least to be able to graphically scroll through previous day’s 24-hour data via bar graphs. #3 set up some type of SMS/email alert when numbers hit a certain number, like 200 or 300. Thanks for the work! Too bad Shanghai doesn’t have something like this…
