Osborn and Briffa 2006 Reconstruction of Spatial Extent of N. Hemisphere Warm and Cold Conditions Osborn, T.J.; Briffa, K.R. Osborn, T.J. Briffa, K.R. Air Temperature Reconstruction earth science/paleoclimate/climate reconstructions (temperature,multiple proxies,null,dimensionless,null,climate reconstructions,normalized|smoothed,null,N,"data series have been smoothed to remove variations on time scales < 20 years,and then normalised to have zero mean and unit standard deviation over 800-1995") earth science/paleoclimate/climate reconstructions (age,null,null,year Common Era,null,climate reconstructions,null,null,N,null) earth science/paleoclimate/reconstructions (Northern Hemisphere>LATITUDE >LONGITUDE ) Records of past temperature, precipitation, and other climate variables derived from paleoclimate proxies. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations.
