Climatic effect of observed changes in atmospheric trace gases at Antarctica

Research output: Contribution to journalArticlepeer-review


The seasonal decline in ozone in the Antarctic atmosphere has been termed the 'Antarctic ozone hole'. Possibly this hole is caused by upper atmospheric wind, due to resumption of high solar activity after the polar night which produces large amounts of ozone-destroying nitric oxide or due to unusual chlorine chemistry at extreme cold temperatures and associated polar stratospheric clouds. Of particular concern is that the observed changes in ozone could be linked to the observed increases in the gases that affect ozone such as methane, nitrous oxide, etc. All these gases affect the climate of the Earth through their so-called 'greenhouse' action. We have examined the nature of the greenhouse effect on polar climate due to observed changes in atmospheric trace gases in Antarctica which are reported here.
