It encompasses the chemistry of the globe, from polluted to “clean,” remote regions and from the region closest to the earth's surface, the troposphere (∼ 10–15 km), through the tropopause (∼ 10–15 km) into the upper   Dynamics studies of atomic and molecular collisions are particularly important to the understanding of energy transfer and chemical reaction processes in gas-phase systems.
