| Summary: | 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. The dataset can be downloaded from: ftp://ftp.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/ljungqvist2010/ljungqvist2010.txt A graphical description of the dataset is given at: http://wattsupwiththat.files.wordpress.com/2010/09/loehle_v_fig1.png Temperaturrekonstruktion för den extratropiska norra halvklotet.
