Northern Hemisphere Extra-Tropics 2,000-year Decadal Temperature Reconstruction

This data description and associated data have been migrated from the ECDS portal to SND’s research data catalogue. This means that the level of documentation may differ from other data descriptions in the catalogue. You can find more information about the migration of data from ECDS to SND here.

Creator/Principal investigator(s):

Description:

Multi-proxy temperature reconstruction for the extra-tropical Northern Hemisphere (90-30°N) during the last two millennia based on 30 palaeotemperature proxy records with annual to multi-decadal resolution. Proxy types include historical documentary records, seafloor sediment records, lake sediment records, speleothem records, ice-core records, varved thickness sediment records, tree-ring width and maximum latewood density records. The reconstruction is presented as decadal anomalies in degrees C relative to the 1961-1990 reference period and provided with quantitative error bars.
