In this study, we build upon this earlier \r\nwork, specifically targeting south-central England, to derive \r\na well replicated oak ring-width composite chronology using \r\nboth living and historical material.  The data-set includes \r\n352 living trees (AD 1629-2009) and 1540 individual historical \r\nseries (AD 663-1925). The period expressed by at least 50 trees \r\nin any year is AD 980-2009.  Calibration experiments identify \r\nthe optimal seasonal predictand target as March-July precipitation \r\n(1901-2007: r2 = 0.33). However, comparison with the long Kew \r\nGardens precipitation record indicates a weakening in tree-growth/\r\nclimate response from ~1800 to 1920 which we speculate may be \r\nrelated to smoke and sulphur dioxide (SO2) emissions at that \r\ntime which may have also contributed to a decrease in tree \r\nproductivity. The time-series derived using the regional curve \r\nstandardisation method to capture lower frequency information \r\nshows a mediaeval period with alternating multi-decade-long dry \r\nand wet periods, with AD 1153-1172 being the wettest reconstructed \r\n20-year period in the whole record. Drier conditions are prevalent \r\nfrom ~1300 to the early sixteenth century followed by a period of \r\nincreasing precipitation levels. The most recent four centuries \r\nof the record appear similar to the mediaeval period with multiple \r\ndecade-long dry and wet periods. The late twentieth century is \r\nthe second reconstructed wettest period. These centennial \r\nhydroclimatic trends are in broad agreement with independent \r\nregional scale hydroclimatic reconstructions from tree-ring \r\n(East Anglia), historical, speleothem and peat water level \r\nproxy archives in the United Kingdom and appear coupled \r\nwith reconstructed sea surface temperature changes in the \r\nNorth Atlantic which in turn influence the Atlantic meridional \r\noverturning circulation and westerly airflow across the UK.
