Short summary

Isoprene, which is emitted from the vegetation, is important to regional air quality. Drought is one of the most important meteorological events that can modulate isoprene emissions by high temperature and low soil moisture. The drought stress impact on isoprene emissions is still uncertain, and we aimed to constrain it in South Korea using observation and model simulation. The results presented in this study may give useful information for future studies on drought stress on isoprene emissions.
