DescriptionAtmosphere gas proportions.svg	Gas proportions in the Earth's atmosphere. The proportion of water vapor (H2O) is variable so it is not represented in this chart, however it averages about 1% in the troposphere.
Date	30 May 2006
Source	Vectorized version of w:Image:Atmosphere gas proportions.gif (originally by Brockert). I SVG'd it a) to make it more international (chemical symbols) b) to make it (hopefully) clearer when rendered as a thumbnail and c) to make it easier to modify.
