Paper Abstract

The spectroscopic method is used to examine anthropogenic change of atmospheric trace gases in the 1.0-3.5-micron region. During 1979-1990, CO2 is found to show an increase of 0.4 percent/yr; for CH4, the figure is 1.1 percent/yr, which is a slight decrease from the 1979-1985 interval. N2O exhibits no trend within an upper limit of 1 ppb/yr. The behavior of CO is dominated by a large seasonal variation, and no reliable trend can be concluded.
