Zusammenfassung |
Carbon monoxide total column amounts in the atmosphere
have been measured in the High Northern Hemisphere (30°-90° N,
HNH) between January 2002 and December 2003 using infrared spectrometers of
high and moderate resolution and the Sun as a light source. They were
compared to ground-level CO mixing ratios and to total column amounts
measured from space by the Terra/MOPITT instrument. All these data reveal
increased CO abundances in 2002-2003 in comparison to the unperturbed
2000-2001 period. Maximum anomalies were observed in September 2002 and
August 2003. Using a simple two-box model, the corresponding annual CO
emission anomalies (referenced to 2000-2001 period) have been found equal to
95Tg in 2002 and 130Tg in 2003, thus close to those for 1996 and 1998. A
good correlation with hot spots detected by a satellite radiometer allows
one to assume strong boreal forest fires, occurred mainly in Russia, as a
source of the increased CO burdens. |
