    Description

    Global emissions of atmospheric CO2 and tropospheric O3 are rising and expected to impact large areas of the Earth’s forests. While CO2 stimulates net primary production, O3 reduces photosynthesis, altering plant C allocation and reducing ecosystem C storage. The effects of multiple air pollutants can alter belowground C allocation, leading to changes in the partial pressure of CO2 (pCO2) in the soil, chemistry of dissolved inorganic carbonate (DIC) and the rate of mineral weathering.
