Alternative methods of data processing in dendroclimatological analysis of larch Larix decidua Mill. from southern Poland

The aim of this study was to assess the impact of climatic factors (temperature and precipitation) on tree ring width of larches from stands localised in southern part of Poland. Total ring as well as early− and latewood widths were taken in consideration. At the beginning authors used only standard processing and methods. Classic approach were insufficient to make some data useful for the correlation analysis, so authors decided to use more robust, custom methods
