metadata.value: This paper presents the results of assessing the influence of the main climatic factors on the
  tree-ring width of Siberian larch (Larix sibirica Ledeb.) growing in the upper basin of the Irtysh
  River. Tree core sampling was carried out on the northern macroslopes of the Sarymsakty,
  Tarbagatai and Southern Altai ranges in Kazakhstan, as well as on the southern macroslopes of
  the Southern Altai ranges in Kazakhstan and China, from three sites on the upper tree line and
  four on the lower tree line. According to the results of dendrochronological analysis, two generalized
  tree-ring chronologies, IRTv and IRTn, were obtained, reflecting the variability of the
  radial growth of Siberian larch in the region of study on the upper and lower tree lines, respectively.
  On the upper tree line, the radial growth of Siberian larch is dependent on the thermal
  regime of the beginning of the growing season (June–July). The analysis of tree-ring growth
  dynamics showed that during 1850–1873, 1881–1900, 1906–1939, 1957–1965 and 1982–1990,
  tree-ring growth at the upper tree line was characterized by lower values. Since 1850 there
  has been a positive trend in the tree-ring growth variability, which indicates better thermal
  conditions since the end of the Little Ice Age. The sufficiently strong climatic signal (r = 0.7)
  makes it possible to use IRTv chronology for temperature reconstruction. On the lower tree
  line the variability of radial tree-ring growth is determined by the dynamics of precipitation
  in the winter-spring-summer period (December–July). The most important aspect of this is
  moisturization during the completion of snowmelt and the beginning of the growing season
  (May–June). Analysis of tree growth dynamics showed that over the past 150 years the moisture
  regime has not changed significantly. The reduced values of tree-ring growth correspond
  to 1850–1859, 1877–1907, 1916–1936, 1944–1951, 1962–1968 and 1973–1992.
