BIRA-IASB studies the Earth's stratosphere by looking at ozone depletion and related key parameters like volcanic aerosols, polar stratospheric clouds and halogenated compounds.
BIRA-IASB also studies Earth tropospheric chemistry, with a focus on natural and manmade emissions, like SO2 and NO2, tropospheric ozone precursors, the relationship to air quality and the evolution of greenhouse gases in support of the Kyoto Protocol.
