> Air quality is terrible. AQI does not lie.

Heh. To get a sense of what the page's numbers might mean, I checked on Kaohsiung, where you can taste gasoline in the air as you walk down the street.

And hey, reported air quality in Kaohsiung is abysmal, so that checks out. Jakarta even looks good by comparison.

AQI appears to have Jakarta pegged at an average "66", which looks pretty respectable for the region. They seem to have much more carbon monoxide than Kaohsiung or Shanghai, but much less fine particulate.
