These observations allow us to provide a continuous long - term record to track the long - term and year - to - year evolution of ozone amounts. (sciencedaily.com)
Images from the latter can show how ozone amounts differ from season - to - season and how clouds are formed over volcanoes on the planet. (ibtimes.com)
While recent trends in stratospheric ozone have been driven largely by increases in halogen abundance resulting from chlorofluorocarbon (CFC) emissions, climate change will play an increasing role in governing ozone amounts in the future, and ozone changes will feed back on climate as ozone is itself a greenhouse gas.
