Ozone cycle overview

WebAbstract. Tropospheric ozone is an important air pollutant and greenhouse gas, and also plays a key role in atmospheric chemistry. Its evolution in the atmosphere is strongly modulated by weather and climate, involving a number of biogenic, chemical, and dynamic processes on a wide range of spatial and temporal scales. WebOzone is extremely valuable since it absorbs a range of ultraviolet energy. When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen …
