ENSO influences trans-Pacific ozone transport from vegetation fires in Southeast Asia

Ding and colleagues revealed that the El Niño-Southern Oscillation (ENSO)-modulated vegetation fires in Southeast Asia, rather than fossil fuel plumes from China, dominate the springtime trans-Pacific transport of ozone across the entire North Pacific Ocean. The study expanded the understanding of the roles of variability in emissions and meteorology on tropospheric ozone. It proves once more how complex the interactions in the climate system are.
