Year-to-year variation of ozone hole over Schirmacher region of East Antarctica: A synopsis of four-year measurement
During the 16th, 21st, 22nd and 23 rd Indian Antarctic expedition conducted in 1997, 2002-03 and 2004 respectively, measurement of columnar ozone have been made using MICROTOPS II Sun-photometer from the Indian station Maitri (70° 45â S, 11° 44â E). It is found that the ozone hole depth fluctuated...
