Analysing climate–growth relationships is one of the key areas in dendrochronological research. Oneproblem however remained unsolved – the discrepancy between the trees continuous growth over thevegetation period and the mean climate variables stretching over much longer periods. Here we presentthe possibility to calculate climate–growth correlations based on daily climate data using variable tempo-ral width together with moving correlations to accommodate for short term as well as long term influenceson tree growth. For the first time this offers the opportunity to acknowledge annual changes in the grow-ing seasonal length and effects of short extreme events. Numerous outputs in data- and graphic-filesallows a comparison of varying periods with significant correlations between climate and tree growth.Furthermore the use of climate scenarios is an optional tool for growth predictions
