Abstract

Measurements of gases desorbed by the vacuum method from the disc ring wood of deciduous trees were carried out. The analysis of gases was performed using a photoacoustic gas-analyzer with a tunable CO₂ laser. The chronologies of residual CO₂ and (CO₂+H₂O) gases of some trees that grew in and around Tomsk (West Siberia) have been obtained. Correlation coefficients of chronologies with temperatures and precipitations for the vegetation period are determined. All the chronologies have cycles with period of 2-4 years. We suppose that the distribution of the residual gases in the discs reflects the annual release of the gases from the stems of the deciduous trees into the atmosphere.
