Tenerife, October 22 (RHC) – The hole in the ozone layer over Antarctica stretched for the third time this year to reach cities in the south of Argentina and Chile according to the Izaña Atmospheric research centre in Tenerife, Canary Islands.
Alberto Redondas, a researcher at Izaña said: “The ozone layer has diminished more than 50% from its normal values and the UV intensity index has jumped from four to ten, according to the 16 October reading when the hole reached the 51 degrees south of Rio Gallegos in Argentinian Patagonia.”
Redondas added that the area affected by the ozone layer hole, including populated areas of both Argentine and Chilean Patagonia, reached a first peak last September 16th.
The maximum ozone layer hole over Ushuaia in Tierra del Fuego was recorded in 2006, when it reached an area of 26 million square kilometers. This year the area has reached 24 million square kilometers, after 2011 marked the end of four years of decline.
