IITKGP (November 29, 2018)

While the world is debating on climate change and global warming, researchers at IIT Kharagpur have given the environmental evangelists a reason to rejoice. A research team from the Center of Oceans, Rivers, Atmosphere and Land Science (CORAL) at IIT Kharagpur have come up with new data confirming that the Antarctic Ozone Hole is on a healing path.

The researchers have collected data from 1979 to 2017, which shows though there was a loss in saturation of Ozone since 1987 over the Antarctic; the saturation of loss at 12-21 km has significantly reduced over the period 2001-2017.

This is the first of its kind research providing detailed long-term (four decades) analysis of Antarctic ozone loss saturation in terms of its first occurrence, timing, spatial differences, vertical spread, inter-annual changes and temporal evolution using high-resolution ozonesondes and satellite measurements inside the vortex for the said period.
