Oxides of nitrogen play an important role in the radical chemistry of the atmosphere and in
the production and destruction of tropospheric and stratospheric ozone. Ozone is a principal …

Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-made
aerosols enhance scattering and absorption of solar radiation. They also produce …

Although only about 10% of all atmospheric ozone is located in the troposphere, it is the main
driver of the photochemical processes which lead to the recycling of most of the gases that …

The probable importance of NO and NO 2 in controlling the ozone concentrations and
production rates in the stratosphere is pointed out. Observations on and determinations of nitric …

While stabilization of CO2 would require a 60-80% reduction in current anthropogenic CO2
emissions, worldwide they actually increased by 2% from 2001 to 2002, a trend, which …

Photodissociation of CSO (and possibly CS 2 ) may provide an interesting stratospheric source
of SO 2 and further conversion of this SO 2 to H 2 SO 4 may contribute significantly to the …

Global warming and many other human-driven changes to the environment are raising concerns
about the future of Earth’s environment and its ability to provide the services required to …

The distribution of the compounds NO, NO 2 , NO 3 , N 2 O 5 , and HNO 3 has been
calculated for different choices of relevant parameters, the values of which are uncertain. An …

Biomass burning is widespread, especially in the tropics. It serves to clear land for shifting
cultivation, to convert forests to agricultural and pastoral lands, and to remove dry vegetation …

Atmospheric aerosols play important roles in climate and atmospheric chemistry: They scatter
sunlight, provide condensation nuclei for cloud droplets, and participate in heterogeneous …
