To
examine concentration variations of atmospheric CO2 in the
sub-tropical region of East Asia, systematic air sampling with subsequent
laboratory analysis has been made in the southernmost part of Japan since June 1993. A time
series of measured CO2 concentrations was analyzed for long-term
trend, seasonal cycle and interannual variability, and the temporal CO2 variations deduced were interpreted in
terms of atmospheric transport and CO2 flux regions.
