The Royal Society has organised a study on ground-level ozone and its impacts, and their coupling to climate change. In this context a series of dedicated global model simulations have been performed to evaluate the ozone air quality in 2050 in response to changing emissions and climate.

In relation to this study this page gives access to the simulations performed with the tropospheric chemistry transport model TM4 driven by operational meteorological data from the European Centre for Medium-Range Weather Forecasts (ECMWF) for the year 2000, in particular to:

• plots of concentrations;
• budgets of tropospheric ozone, carbon monoxide, and atmospheric methane.

The report "Ground-level ozone in the 21st century: future trends, impacts and policy implications" can be found at the Royal Society.
