Multiproxy Data Network

The various records contributing to the multiproxy network are indicated along with type of proxy (e.g., instrumental or historical, dendroclimatic, coral, ice core), climate variable (or probable climate variable) inferred, first year (AD) of record available, and the reference/authors for the data. All data are annual resolution (or annual mean in the case of instrumental data available at higher resolution). Small gaps have been interpolated. If records terminate slightly before the end of the 1902-1980 training interval, they are extended by persistence to 1980. Certain proxy datasets have been represented by a smaller number of leading principal components of the set (PCs) the maximum number of which (available back to 1820) are indicated in parentheses. Information for data taken from the International Tree Ring Data Band (ITRDB) is provided in a different abbreviated format. More information and complete references for these data can be found on a separate web location sponsored by the National Geophysical Data Center (NGDC): http://www.ngdc.noaa.gov/paleo/treering.html
