Ozone can be “good” or “bad” for health and the environment depending on where it’s found in the atmosphere. 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.
