Variability in sun photometer derived summertime total column ozone over the Indian station Maitri in the Antarctic region
Extensive observations of total column ozone (TCO) made over the Antarctic region at the Indian station 'Maitri' (70.76oS, 11.74oE) during two summer periods of 2004-2005 and 2006-2007 using a ground-based optical remote sensing instrument (ozonometer) have been examined to study the short...
