regression by using linear spline regression and a likelihood-based model to explain nonlinearity in the relationship between tree rings and precipitation. One of the most accurate and tested process-based models, the Vaganov-Shaskin model ( VS model, Shishov et al ., 2016 ; Vaganov et al ., 2011 ), uses a piecewise linear function to model the relationship between daily environmental data and tree-rings. A similar idea is implemented in a simplified version of the VS model – the VS-Lite model ( Tolwinski-Ward et al ., 2011 ). The advantages of using nonlinear models

-OSL simply implies that the charge responsible for emission originates from the deep trap and not the mechanism involved in OSL process. This is necessary to differentiate from the conventional OSL (325°C TL Peak). The dosimetric properties of DT-OSL were found to be good in terms of linearity and upper limit of dose estimation. The signal also satisfied various tests needed for reliable use dose estimation.
The luminescence measurements were carried out on automatic Risø TL/OSL, TL-DA-15 system having a blue light-emitting diodes (λ=470 ± 30nm

( Visocekas and Guerin, 2006 ). It has been presumed that anomalous fading results from tunnelling of charge that follows strict physical laws, i.e. the signal decays logarithmically ( Visocekas, 1985 ). Following these assumptions, Huntely and Lamothe (2001) developed a procedure to correct for fading. First, storage experiments are carried out to monitor the loss of signal with time. The results of such experiments are expressed by g -values, where g is the signal loss in percent per decade, a decade being a factor of 10 in time since irradiation (Huntely and Lamothe
salt samples are manufactured on the same production line they have similar luminescence characteristics, although some slight sensitivity changes may occur, and so are amenable to evaluation using a standardized testing protocol.
