A quantitative high - resolution summer temperature reconstruction based on sedimentary pigments from Laguna Aculeo , central Chile , back to AD 850

et al., 2006). While significant advances have been made in the reconstruction methods and compilation of data sets for the Northern Hemisphere (Mann et al., 1999; Luterbacher et al., 2004; Moberg et al., 2005; Lee et al., 2008), the Southern Hemisphere is largely ‘terra incognita’ and devoid of adequate data. For the entire Southern Hemisphere, Mann and Jones (2003) considered only five data sets suitable for their work on surface temperature reconstructions for the past two millennia. Introduction
