Caption

Climate shifts and a sudden rise in Asian ozone pollution reaching Hawaii during autumn in the mid-1990s onwards are documented in the figure. Shown are tracer of Asian pollution in 2010 (the inset map) and times series of autumnal ozone anomalies at Mauna Loa, Hawaii, for 1975 to 2012 as observed (black) and simulated by a chemistry-climate model with constant (red) and time-varying (purple) emissions of ozone precursors.
