NOAA National Centers for Environmental Information - Paleoclimatology Data

Paleoclimatology data are derived from natural sources such as tree rings, ice cores, corals, and ocean and lake sediments. These proxy climate data extend the archive of weather and climate information hundreds to millions of years. The data include geophysical or biological measurement time series and some reconstructed climate variables such as temperature and precipitation. NCEI provides the paleoclimatology data and information scientists need to understand natural climate variability and future climate change. We also operate the World Data Center for Paleoclimatology, which archives and distributes data contributed by scientists around the world.

古气候学数据源自于自然源，如树木年轮、冰芯、珊瑚以及海洋和湖泊沉积物。此类代理气候数据将气候与气象信息的档案延伸至数百至数百万年。数据包括地球物理或生物测量时间序列，以及一些重构的气候变量，例如温度和降水量。国家气候数据中心提供古气候学数据和信息，以满足科学家们理解自然气候变率和未来气候变化的需求。此外，我们还负责运营世界古气候数据中心，该中心负责收集和分发全球科学家贡献的数据。
