WebAtmospheric dynamics and composition encompass the physical and chemical processes in the atmosphere related to weather, air quality, and climate. The interplay between atmospheric dynamics and composition can be seen, for example, in the rapid uplift of pollution from the Earth’s surface in convective storms and subsequent long-range ... WebTerra and Atmospheric Composition Terra is the first satellite to provide integrated measurements of the processes connecting the atmosphere to emissions from activity on the ground. For example, Terra instruments measure both fires and smoke. In particular, Terra instruments measure aerosols (particles in the atmosphere) and carbon monoxide.
