Abstract

Relative to a standard one-foot diameter globe of the Earth the thickness of the atmosphere is comparable to a sheet of plastic food warp covering the globe. Within this thin, fluid membrane long established balances in chemical and radiative processes are being altered by anthropogenic activities. For instance, each year about 50% of the carbon dioxide (CO₂) produced by the combustion of fossil fuels and burning of forests remains in the atmosphere. This 1% yr^-1 increase in CO₂ traps solar energy leading to a rise in atmospheric temperatures known popularly as 'greenhouse warming.' Halocarbons from escaped refrigerants and other sources are destroying the stratospheric ozone layer allowing increased levels of UV to reach the Earth's surface. To monitor these changes in the atmosphere, a global network of atmospheric baseline stations tracks the health of the atmosphere. Some manned stations are in weather challenged locations such as the South Pole, Spitzbergen, Ellesmere Island and the Tibetan Plateau; others are in more benign climates such as Hawaii, Samoa, Tasmania, Reunion, and Kenya. Data from these and others stations are presented and discussed.
