Yamal_All chronology indices

Individual-tree index series produced as fractional deviations from a single "all-site" (i.e. Yamal_All) RCS curve. The equivalent indices (from the same trees but standardised with different RCS curves) made up the modern parts of the Briffa (2000) and Briffa et al. (2008) chronologies. Note that the data for the 5 uppermost series are those not selected for substitution in McIntyre's analysis and the raw measurements, therefore, are included for convenience among the "sub-fossil" data common to all chronologies except those based only on local site data (i.e. for POR, YAD, JAH and KHAD).
The individual-tree index series for the JAH site produced as fractional deviations from a single "all-site" (i.e. Yamal_All) RCS curve. Note that not all trees show the relative increase in growth in the late 20th century that is characteristic of the data set as a whole.
The individual-tree index series for the POR site produced as fractional deviations from a single "all-site" (i.e. Yamal_All) RCS curve.
The individual-tree index series for the YAD site produced as fractional deviations from a single "all-site" (i.e. Yamal_All) RCS curve. Note that not all trees show the same relative increase in growth in the late 20th century that is characteristic of the data set as a whole.
The individual-tree index series for the KHAD site produced as fractional deviations from a single "all-site" (i.e. Yamal_All) RCS curve. Note that the gaps in some series occur because these ring-width data were acquired from densitometric measurements of sample cores and not from direct measurement of ring width.

Miscellaneous RCS and chronology data

For files with "crn" suffix the data are in Tucson Index format. The header lines contain a brief description of the standardisation options used and the meaning of the descriptors are:
RCM= Mean ring width by age
RCS= Smoothed RCS curve
STD= Standard chronology
CSM= Smooth chronology
CSD= Chronology standard deviation
SPL= High-pass filtered chronology

Additional tree-ring data from this region

Additional tree-ring width data reported by Vaganov, E.A., Shiyatov, S.G., and Mazepa, V.S. (1996: Dendroclimatic study in Ural-Siberian Subarctic. Novosibirsk: Nauka, 246 pp., in Russian) are available here though they have not been used in the Yamal sensitivity studies described in these web pages.
