Weekly air samples taken during the past decade at sites ranging in latitude from 71.5 deg N to 71.4 deg S are considered in order to detect the presence of such trace gases as molecular hydrogen. The data presented in the study is monthly averaged concentration of each site between October 1985 and April 1989 from about 3500 weekly air samples. It is shown that the concentration of H2 increased at an average rate of 3.2 +/- 0.5 parts per 10 to the 9th by volume per year, and that trace gases affected by human activities are normally more concentrated in the Northern Hemisphere, but the average ground-level distribution of hydrogen is the opposite. Because the oxidation of hydrogen contributes substantial amounts of water vapor to the stratosphere, increasing hydrogen may already be contributing to increases in stratospheric water vapor.
