ATMOSPHERIC CHEMISTRY

The area of atmospheric science known as atmospheric chemistry focuses on the chemical reactions that take place in the Earth's atmosphere. Improved knowledge of climate forcing, air quality, and the interactions between the atmosphere and biosphere depend on research in this field. Chemists including Joseph Priestley, Antoine Lavoisier, and Henry Cavendish performed the initial observations of the atmospheric composition in the 18th century, which marked the start of the first scientific investigations into atmospheric composition.  The chemistry of the atmosphere is crucial in regulating climate change; for instance, aerosol particles have an impact on the climate directly through radiative forcing, indirectly through clouds, and directly through carbon uptake.
