A burning question. Can recent growth rate anomalies in the greenhouse gases be attributed to large-scale biomass burning events?

摘要

Simultaneous in situ measurements of carbon dioxide (CO2) and the principal gases linked to biomass burning at the Mace Head Observatory, Ireland, reveal a strong correlation in 1998-99 and 2002-03, both periods with intense global fires. CO2, carbon monoxide (CO), methane (CH4), hydrogen (H-2), ozone (O-3) and methyl chloride (CH3Cl), all have similar rates of accumulation during these time frames. These perturbations imply a causal relationship between large-scale biomass burning events and the interannual variability of these gases. (c) 2005 Elsevier Ltd. All rights reserved.
