About NOAA Paleoclimatology • NOAA’s National Climatic Data Center is the world's largest archive of climate and paleoclimate data. • The Paleoclimatology Branch operates the World Data Center for Paleoclimatology, which is one of 52 World Data Centers that house a wide range of solar, geophysical, environmental, and human dimensions data, and the only World Data Center devoted to paleoclimatic data. NCDC - Asheville Paleo Branch - Boulder
About NOAA Paleoclimatology • We follow standardized guidelines for data archive and distribution developed by the International Council for Scientific Unions (ICSU), supporting the ICSU goal to strengthen international science for the benefit of society, and making all data freely available without restriction. • We archive information so that it can be used by paleoclimate experts, scientists from other fields, resource managers and decision-makers, students, educators, and interested citizens -- in short, by anyone interested in gaining a better understanding of long-term variations in climate and environment.
