LOTRED-SA (Long-term climate reconstruction and diagnosis in South America) is a new PAGES research initiative. This collaborative effort aims at collating existing data sets to produce a comprehensive high-resolution multi-proxy reconstruction of regional climate in South America over the last few millennia. Hosted by the city of Malargüe, Argentina and organized by PAGES, the Instituto Argentino de Nivologia, Glaciologia y Ciencias Ambientales (IANIGLA) and the University of Bern, Switzerland, LOTRED-SA held its first science conference from 4-7 October 2006. 133 scientists from 17 countries (mainly from Argentina, Chile, Brazil, Switzerland and USA, among them many members of the PAGES Scientific Steering Committee) joined for review keynotes, and oral and poster presentations of new paleoclimate data sets and research activities. The objective of the conference was to gather experts from different fields in climate dynamics, diagnosis and paleoclimatology (data and models) to review the existing knowledge and data sets, to discuss the interpretation of natural and documentary proxy data, to search for calibration and quantification techniques of proxy data sets in South America, and to discuss the implementation plan for the PAGES Research Initiative LOTREDSA. The long-term goal and vision of this collaborative effort is to work towards a comprehensive view of regional climate variability and environmental change back in time (ca. 1000 years), and to produce a gridded data set of climate variables from high-resolution (sub-decadal) multi-proxy time series.
