NASA GISS Surface Temperature (GISTEMP) Analysis

The NASA GISS Surface Temperature (GISTEMP) analysis provides a measure of the changing global surface temperature with monthly resolution for the period since 1880, when a reasonably global distribution of meteorological stations was established. The input data that the GISTEMP Team use for the analysis, collected by many national meteorological services around the world, are the adjusted data of the Global Historical Climatology Network (GHCN) Vs. 3 (this represents a change from prior use of unadjusted Vs. 2 data) (Peterson and Vose, 1997 and 1998), United States Historical Climatology Network (USHCN) data, and SCAR (Scientific Committee on Antarctic Research) data from Antarctic stations. Documentation of the basic analysis method is provided by Hansen et al. (1999), with several modifications described by Hansen et al. (2001). The GISS analysis is updated monthly, however CDIAC's presentation of the data here is updated annually.

美国国家航空航天局（National Aeronautics and Space Administration, NASA）戈达德太空研究所（Goddard Institute for Space Studies, GISS）地表温度（GISTEMP）分析项目，提供了自1880年以来全球地表温度变化的逐月分辨率数据集——1880年时，全球气象站已形成较为合理的分布格局。该分析所用的输入数据由全球多国气象服务机构收集，具体包括经校正后的全球历史气候学网络（Global Historical Climatology Network, GHCN）第3版数据（相较于此前使用的未校正第2版数据，本次版本已完成调整，相关说明参见Peterson与Vose分别于1997年、1998年发表的研究成果）、美国历史气候学网络（United States Historical Climatology Network, USHCN）数据，以及南极研究科学委员会（Scientific Committee on Antarctic Research, SCAR）提供的南极观测站数据。基础分析方法的相关文档由Hansen等人于1999年发布，后续Hansen等人在2001年对该分析方法作出了多项修订。GISS的分析结果按月度更新，不过美国碳数据信息分析中心（Carbon Dioxide Information Analysis Center, CDIAC）在此展示的数据则按年度更新。若需获取数据文件，请点击此链接跳转至CDIAC数据过渡网站：http://cdiac.ess-dive.lbl.gov/trends/temp/hansen/hansen.html
