Description
Jinghui Ma and co-authors rebuild, in a 2025 study, a missing stretch of ground-level ozone records for central and eastern China. Ozone harms lungs and ecosystems, yet records before 2013 are scarce in that region. The team filled the gap from 1980 to 2012.
A machine learning model trained on many data sources produced daily peak ozone values on a fine grid. Checks against later real observations showed strong agreement across most grids. The rebuilt record shows a regional mean with a clear north-south gradient. Long records like this let scientists judge whether recent clean-air gains reverse older trends. They also support health studies that need exposure history, not just today's air.
