Brief Description (Abstract):
Measurement of surface air concentration of methane and carbon dioxide has been carried out using Automated Gas Chromatograph at Indian research Station, Maitri (70?.44'S, 11?.45'E), Antarctica during 21s1 and 22nd Indian Scientific Expedition to Antarctica. Very small day-to-day variation of surface CH4 concentration was observed during observational period. The mean CH4 concentration for sixteen-month period (February 2003 to June 2004) was found out to be 1.70 ppm. The averaged C02 concentrations were found out to be 368.32 ppm and 369.51 ppm in the year 2002 and 2003 respectively. The values of CO, observed over Maitri are comparable to present Global CO, value. In present communication experimental setup and results obtained are discussed in detail.
Status: Completed
Purpose: The distribution of greenhouse gases in the atmosphere, particularly those due to human and biosphere activities, is quite heterogeneous. The growth of the atmospheric concentration levels of greenhouse gases since the industrial period (1750) such as carbon dioxide, methane, nitrous oxide, halo carbons and tropospheric ozone has been identified as one of the major causes of the warming of the Earths surface.
