Air Quality Index

The east coast experienced some record breaking weather on June 7 and June 8. In NYC, the peak of the Air Quality Index (AQI) of fine particles at one point was 460.

As a result, I had been keeping a close eye on the value for those few days and discovered to my surprise that I already had an API Key for AirNow data.

Which then sparked a one night project that blossomed from just my location to also showing data for a particular zip code.

The result can be found here (for my hometown) and then you can view for your location by zip code by using your zip code in the URL.

Luckily, we already had an air purifier in the house and felt pretty good about being indoors. Our entire family spent two nights sleeping in the same room -- almost like camping!
