The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Norway, Scandanavia. The time period coverage is from 960 to -51 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

(Scots Pine). Individual isotope series were corrected for changes in, the isotopic ratio and concentration of, atmospheric CO2 over the industrial period (since AD1850). The mean isotope series was calibrated against observed percentage cloud cover from Tromsø, over the period AD1890-2001 (R2, 0.46). The mean isotope series was then scaled to Tromsø cloud cover to produce a 1010-year reconstruction of percentage cloud cover. See Young et al. (2010; 2012) for full details. Forfjorddalen, Forfjord, Vesterålen, Northern Norway: 68°48'N, 15°44'E IITRDB005 ABSTRACT SUPPLIED BY ORIGINATOR: Cloud cover currently represents the single greatest source of uncertainty in General Circulation Models. Stable carbon isotope ratios (d13C) from tree-rings, in areas of low moisture stress, are likely to be primarily controlled by photosynthetically active radiation (PAR), and therefore should provide a proxy record for cloud cover or sunshine; indeed this association has previously been demonstrated experimentally for Scots pine in Fennoscandia, with sunlight explaining ca 90% of the variance in photosynthesis and temperature only ca 4%. We present a statistically verifiable 1011-year reconstruction of cloud cover from a well replicated, annually-resolved d13C record from Forfjord in coastal northwestern Norway. This reconstruction exhibits considerable variability in cloud cover over the past millennium, including extended sunny periods during the cool seventeenth and eighteenth centuries and warm cloudy periods during the eleventh, early fifteenth and twentieth centuries. We find that while a generally positive relationship persists between sunshine and temperature at high-frequency, at lower (multi-decadal) frequencies the relationship is more often a negative one, with cool periods being sunny (most notably the Little Ice Age period from 1600 to 1750 CE) and warm periods more cloudy (e.g. the mediaeval and the twentieth century). We conclude that these long-term changes may be caused by changes in the dominant circulation mode, likely to be associated with the Arctic Oscillation. There is also strong circumstantial evidence that prolonged periods of high summer cloud cover, with low PAR and probably high precipitation, may be in part responsible for major European famines caused by crop failures.
