Fig. 3: 2005-2019 greening effects on ozone air quality over South China in the growing season.
From: Co-benefit of forestation on ozone air quality and carbon storage in South China
a–c Spatial distributions of maximum daily 8-hour average (MDA8) ozone concentrations (a), monthly vegetation ozone exposure metric of AOT40 (b), and ozone-induced gross primary productivity (GPP) damage (c) over China in 2019 simulated in the WRF-Chem Base model. d–f Changes in surface MDA8 ozone concentrations (d), monthly AOT40 (e), and ozone-induced GPP damage with considering LAI-induced GPP changes (f) due to the 2005-2019 greening effects. Circles in (a) and (b) denote measured MDA8 ozone concentrations and monthly AOT40 at the China Ministry of Ecology and Environment (MEE) national network. Mean observed values (OBS), corresponding base simulated results (MOD), and their spatial correlation coefficient (R) are shown as inset.
