Air of the Anthropocene
The artist Robin Price has been working with the environmental atmospheric scientist Francis Pope on creating images that show air pollution that would otherwise be invisible.
What do the picture captions mean? Each picture is captioned with a reading of the amount of PM2.5 particles at the time the image was made measured in micrograms per cubic metre. PM2.5 stands for particulate matter smaller than 2.5 microns in width which is the size that are hazardous to human health.
