. A reconstruction of hydroclimate with an annualresolution covering millennia for a geographically limited region incontinental Europe significantly improves our knowledge of past climatedynamics. With the use of an extensive collection of oak ring-width series(Quercus robur and Quercus petraea) from living trees, historic timbers and subfossil alluvial wooddeposits from the Main River region in southern Germany, a regional,2000-year long, seasonally resolved hydroclimate reconstruction for theMain region has been developed. Climate-growth response analysis has beenperformed with daily climate records from AD 1900 onwards. To test thestability of the developed transfer function, a bootstrapped transferfunction stability test (BTFS) as well as a classical calibration/verification approach have been implemented to study climate-growth modelperformance. Living oak trees from the Main River region show a significantsensitivity to the precipitation sum from 26 February to 6 July (spring tomidsummer) during the full (r=0.49, p&lt;0.01, N=116) andsplit (r=0.58, p&lt;0.01, N=58) calibration periods. BTFSconfirmed the stability of the developed transfer function. The developedprecipitation reconstruction reveals high variability on a high- tomid-frequency scale during the past two millennia. Very dry spring tomidsummer seasons lasting multiple years appeared in the decades AD 500/510s, 940s, 1170s, 1390s and 1160s. At the end of the AD 330s, apersistent multi-year drought with drastically reduced rainfall (with regard to 1901–2000) could be identified, which was the driest decade over the past2000 years in this region. In the AD 550s, 1050s, 1310s and 1480s,multi-year periods with high rainfall hit the Main region. In spring tomidsummer of AD 338, precipitation was reduced by ∼38 %and in AD 357 it increased by ∼39 %. The presentedhydroclimate reconstruction and its comparison to other records revealinteresting insights into the hydroclimate dynamics of the geographicallylimited area over the Common Era, in addition to revealing noticeable temporaldifferences.
