Abstract

The troposphere comprises roughly the lowest 10 km of the atmosphere, the part we inhabit, that envelops us, and that we inhale and look through every day of our lives. Clouds, rain, all manner of storms, and other aspects of weather originate within it, and it contains 85% of the mass of the atmosphere, including aerosol particles. These particles, like greenhouse gases, can influence climate. Mineral particles ale major constituents of this aerosol. Their sizes, shapes, compositions, and degrees of agglomeration can all be determined using transmission electron microscopy. These variables have, to a considerable extent, been overlooked in studies of atmospheric chemistry and provide an important potential area of research for geoscientists.
