European Gridded and Regional Summer Temperature ReconstructionsEntry ID: NOAA_NCDC_PALEO_2002-069
Abstract: ABSTRACT (from the online documentation):
Temperature variations over Europe are reconstructed for a 6-month "summer"
season from April to September for the period 1750-1850 using a network of
maximum latewood density chronologies of coniferous trees. Around 44% of the
variance of the whole temperature grid was explained in calibration.
Independent verification indicates that over the ... reconstruction period the
explained variance averaged over the whole grid should lie in the range 30 to
35%. The reconstructions are better in the north of the region (about 55%
explained temperature variance based on comparison with independent climate
data) than in the south (below 20%). The temperature reconstructions indicate
cooler summers over Europe from 1812 to 1816 and during the 1830s. The summers
of the 1820s were the warmest reconstructed. Decadal variations occur on a
regional scale but no similar periods of anomalously cooler of warmer summers
occurred between 1750 and 1810 throughout Europe.
Data consists of European gridded and regional summer temperature
reconstructions, based on a network of maximum latewood density chronologies of
coniferous trees. Data also contains 25 individual grid point reconstructions
plus three regional mean series for United Kingdom, Scandanavia, and Central
Europe. Data runs from 1750 - 1975, and are degrees Celsius anomalies from the
base period 1951-70.
