Cause of a lower-tropospheric high-ozone layer in spring over Hanoi

Ogino, S., Miyazaki, K., Fujiwara, M., Nodzu, M., Shiotani, M., et al. (2022). Cause of a lower-tropospheric high-ozone layer in spring over Hanoi. Journal of Geophysical Research: Atmospheres, doi:https://doi.org/10.1029/2021JD035727

The ozonesonde observations in Hanoi, Vietnam, over 14 years since 2004, have confirmed an enhancement in lower tropospheric ozone concentration at about 3 km altitude in the spring season. We investigated the evolution of the ozone enhance...
