A caution we publish daily

Gas readings carry documented unit-inconsistency at absolute levels (peer-reviewed international research, 2025); but this CO year-on-year uses the same stations + units as last year, so the DIRECTION of the rise is reliable. Today leads on PM2.5/PM10; gas is context only.
