Paper Abstract

With increasing awareness of the potential for changes in the earth's environment through natural and artificial mechanisms comes an enhanced desire to globally monitor more regions of the atmosphere. The chemical state of the troposphere is recognized as a significant area, although one where it is extremely difficult to make measurements due to the interfering effects of clouds and the nearby surface. The measurements of pollution in the troposphere (MOPITT) instrument uses the principle of correlation spectroscopy to measure carbon monoxide (CO) amounts at three levels in the troposphere utilizing thermal radiation at 4.7 micrometers and the total column amount of CO and methane (CH4) using reflected sunlight around 2.4 micrometers . The MOPITT instrument will fly on the AM-1 platform of NASA's Earth observing system (EOS) program in mid-1998. The instrument is being funded by the Canadian Space Agency (CSA) and the data processing by NASA. MOPITT has an international science team with members from Canada, the USA, and the UK.
