Variations in Ring Width and Gas Components in Wood of Larch Trees Injured by the Fire of 1908

The CO 2 content in tree wood and the radial increment of trees can change under the impact of ground fires. The study of discs of larches survived the fire of 1908 after the explosion of the space body in the Podkamennaya Tunguska region revealed a number of features in the behavior of absorbed CO...

Description
Summary:The CO 2 content in tree wood and the radial increment of trees can change under the impact of ground fires. The study of discs of larches survived the fire of 1908 after the explosion of the space body in the Podkamennaya Tunguska region revealed a number of features in the behavior of absorbed CO 2 and (CO 2  + H 2 O) in the larch wood. The photoacoustic analysis of vacuum-desorbed samples from tree rings shows a long-term annual accumulation of CO 2 and (CO 2 + H 2 O) in tree stems after 1908. A change in CO 2 release cycling in the postcatastrophic period is ascertained. A change in variation cycling is also noted in the tree ring chronologies. According to the analysis of the correlation coefficients, the specific behavior of the larch ring width chronologies in this region is most likely due to variations in solar activity.
