Abstract
A photoacoustic method was used to analyze gas samples vacuum-extracted from larch discs that survived the explosion of a space body in the Podkamennaya Tunguska area in 1908. The specificity of СО2 accumulation in tree rings after the catastrophe was revealed, which could affect the dynamics of СО2 emission by the trunks into the atmosphere.
