Tropospheric ozone in CMIP6 simulations
Listed in National Center for Atmospheric Research
The evolution of tropospheric ozone from 1850 to 2100 has been studied using data from Phase 6 of the Coupled Model Intercomparison Project (CMIP6).
Description
We evaluate long-term changes using coupled atmosphereâocean chemistryâclimate models, focusing on the CMIP Historical and ScenarioMIP ssp370 experiments, for which detailed tropospheric-ozone diagnostics were archived. The model ensemble has been evaluated against a suite of surface, sonde and satellite observations of the past several decades and found to reproduce well the salient spatial, seasonal and decadal variability and trends.
The multi-model mean tropospheric-ozone burden increases from 247â±â36âTg in 1850 to a mean value of 356â±â31âTg for the period 2005â2014, an increase of 44â%. Modelled present-day values agree well with previous determinations (ACCENT: 336â±â27âTg; Atmospheric Chemistry and Climate Model Intercomparison Project, ACCMIP: 337â±â23âTg; Tropospheric Ozone Assessment Report, TOAR: 340â±â34âTg).

In the ssp370 experiments, the ozone burden increases to 416â±â35âTg by 2100. The ozone budget has been examined over the same period using lumped ozone production (PO3) and loss (LO3) diagnostics. Both ozone production and chemical loss terms increase steadily over the period 1850 to 2100, with net chemical production (PO3-LO3) reaching a maximum around the year 2000.
The residual term, which contains contributions from stratosphereâtroposphere transport reaches a minimum around the same time before recovering in the 21st century, while dry deposition increases steadily over the period 1850â2100. Differences between the model residual terms are explained in terms of variation in tropopause height and stratospheric ozone burden.
