Remote Sensing of Tropospheric Carbon Monoxide

Satellite remote sensing offers the best opportunity of making global measurements of tropospheric trace gases and aerosol over extended periods of time. However, “seeing” the troposphere presents major challenges that are only just being met. Until now, studies have relied on field campaigns, regular groundbased and aircraft measurements from specific sites, and an important input from chemical-transport modeling. This paper will review the contribution of the Terra/MOPITT mission to our understanding of anthropogenic emissions of carbon monoxide, the subsequent tropospheric transport, and the impact on regional and global scale air quality and chemistry. The way in which these measurements have been used to in conjunction with a chemical transport model to provide top-down emissions estimates will also be discussed.
