Abstract

During the Large-Scale Biosphere-Atmosphere Experiment in Amazonia wet season experiment, the near-surface measurements of equivalent potential temperature and ozone at night, when background levels of ozone are low, clearly show that convective downdrafts rapidly transport air with higher ozone and lower equivalent potential temperature down to the surface from around 800 hPa. This largely unreported downward transport of ozone may play a significant role in the photochemistry of the atmosphere boundary layer and increase the surface deposition of ozone.
