| Abstract: | Measurement of total column water vapour made over Maitri (70.44°S, 11 .45°E), Antarctica, using MICROTOPS-II sun-photometer during 2002 showed that the monthly average concentration of water vapour varied from 0.67 cm to 0.18 cm. Water vapour concentration was found varying significantly with season and time of the day. The measurements carried out during 1997, 2002 and 2003 during voyage from Delhi to Antarctica revealed that the concentration of water vapour decreases with increasing latitudes. Water vapour concentration was also found to be in correlation with corresponding temperature. The water vapour over Antarctica was also compared with that over Delhi as well as with high altitude stations, Leh (34°15ʹN, 77o 56ʹE, 3.311 km amsl), and Hanle (32°47ʹN, 78°58ʹE, 4.50 km amsl), which showed that the concentration of water vapour at Leh, Hanle and Maitri is of same order and very low compared to that over Delhi. |
