Each day's ranked cities split by band, worst at the top: a taller red and purple share means a worse day for more of the world, not just one city.

Climbing fastest

Movement shows once the board is a day old.

Cleanest air

Cities with reference monitors only.

What's missing

We rank only cities whose monitor data we're allowed to reuse. The government monitoring networks of China and Turkey publish no terms that allow this, so we leave them out: most cities there are missing here, not clean. The few of their cities that appear are measured by community low-cost sensors, tagged as such. Why.
