Short summary

We quantify the impacts of anthropogenic and natural sources on free tropospheric ozone over the Middle East, using the adjoint of the GEOS-Chem model with updated NO_x emissions estimates from an ensemble Kalman filter. We show that the global total contribution of lightning NO_x on free tropospheric O₃ over the Middle East is about 2 times larger than that from global anthropogenic sources. The summertime free tropospheric O₃ enhancement is primarily due to Asian NO_x emissions.
