It is clear that fundamental research progress in atmospheric chemistry continues across a broad front.
Results have application from local air quality to climate change.
It is not surprising that much attention is still given to stratospheric ozone and greenhouse gasses. Research results in both of these areas continue to have a substantial influence on the activities of the nations of the world. Progress in understanding the importance of atmospheric aerosols in the global climate has been substantial during this time period, which is the main reason for a separate article on this critical subject.
