Terrestrial ecosystem is ‘breathing’ all the times, thus leading to the gas exchange between atmosphere and biosphere. Beyond the most well-known fluxes of CO2, O2 and water, many chemical components with relatively lower abundance, such as N-related gases, ozone and volatile organic compounds (VOCs), are often overlooked, but they still significantly affect terrestrial ecosystem functioning, air quality and climate changes. By bridging the knowledge in the modelling of atmospheric chemistry and terrestrial biosphere, here I will summarize my past and ongoing work focusing on the interactions among atmospheric chemistry, terrestrial biosphere and climate, and discuss 1) how such interactions influence the radiative balance of atmosphere and further affect climate; 2) what are the impacts of atmospheric chemical components on terrestrial carbon productivity; and 3) the contributions of terrestrial ecosystem on extreme air pollutions.
