MODEL ESTIMATIONS OF THE EFFECT OF SIBERIAN STRONG FIRES ON ATMOSPHERIC COMPOSITION AND REGIONAL CLIMATE DURING 2002-2003 WARM PERIODS

摘要

The strong large scale fires due to hot weather over Siberia during the 2002-2003 warm seasons were recorded. They caused a substantial intensification of atmospheric pollution by various combustion products, including CO, NO), = NO + NO2 and numerous aerosol types. An increase of North Asia CO emissions by -30-70% in warm seasons has been estimated for 2002 and 2003 due to the aforementioned fires. The GOME measurements of the NO2 vertical tropospheric column over China (30- 40° N, 110-123° E) show its significant growth after 2000-2001 reaching 15-40% in various months.
