Increased Northern Hemispheric Tropospheric CO Burden in 2002 And 2003 Detected From the Ground and From a Satellite
Abstract
Carbon monoxide total column amounts in the atmosphere have been measured between January 2002 and December 2003 in the High Northern Hemisphere (30°-90° N, HNH) using infrared spectrometers of high and moderate resolutions. They were compared to the mixing ratios measured in the surface layer and to the total column amounts measured by the Terra/MOPITT instrument. All the data reveal increased CO abundances in comparison with other years. Maximum anomalies (deviations from the "normal" monthly means, averaged over 2000- 2001 or over 1996 - 2001) were observed in October 2002 and August 2003. Nonetheless, these enhancements were twice as little comparing to the record high CO anomaly in October 1998. Most likely, CO emissions from the strong boreal forest fires in Russia and in Canada induced increasing CO burdens.
