New GC Letter: Visualising historical changes in air pollution with the Air Quality Stripes

1 October 2025

The Air Quality Stripes images visualise historical changes in particulate matter air pollution in over 150 cities worldwide. The project celebrates significant improvements in air quality in regions like Europe, North America, and China while highlighting the urgent need for action in areas such as central Asia. Designed to raise awareness, the images aim to inspire discussions about the critical impact of air pollution and the global inequalities it causes.

Executive editor's statement: The concept of Air Quality Stripes presents a novel visualization method for historical air pollution.
