Abstract

Carbon monoxide is an excellent indicator of gaseous emissions from biomass burning. Boreal forest/peat fires in the Northern Hemisphere occur in spring and summer every year, but the severity of fires varies significantly. The fire seasons of 2002 and 2003 with record intense Siberian fires were followed by record North American fires in 2004 and the relatively weak fires in 2005 both in North America and Eurasia. We present a first look at tropospheric CO data obtained in 2006 and correlate this data with the occurrence of boreal fires. We will find the place of the 2006 season in the `ranking' of the previous 10 years fire intensity. CO measured from satellites (AIRS/Aqua and MOPITT/Terra) as well as from the ground (Zvenigorod, near Moscow, Russia) will be analyzed and compared. As an example, a case, which occurred in July, will be discussed. CO was emitted at Central Siberia in mid-July and then transported to the Northwest to the Arctic. After that the plume returned to the continent and was detected over Zvenigorod using a ground based spectrometer. Motion of the plume also was tracked by aerosol index measurements from OMI/Aura.
