Global and Hemispheric Annual Temperature Variations Between 1854 and 1991 (revised 1994) (NDP-022)

This data set contains estimates of global and hemispheric annual temperature variations, relative to a 1950 through 1979 reference period, for 1861 through 1991. The estimates are based on corrected land and ocean data. Land data were derived from meteorological data and fixed-position weather-ship data that were corrected for nonclimatic errors, such as station shifts and/or instrument changes. The marine data used were those in the Comprehensive Ocean-Atmosphere Data Set (COADS) compilation, which with updates covers to 1986. Updates to 1991 were made with hemispheric sea-surface temperature estimates produced by the U.K. Meteorological Office. Each record includes year and six annual temperature variations: one estimate each for the globe, the Northern Hemisphere, and the Southern Hemisphere and another estimate each that reflects an adjustment to account for the influence of El Niño/Southern Oscillation events. The data are in one file of 13 kB. For access to the data files, click this link to the CDIAC data transition website: http://cdiac.ess-dive.lbl.gov/ndps/ndp022.html

本数据集包含1861年至1991年间，以1950年至1979年为参考时段的全球及各半球年温度距平估算值，其估算基于经校正的陆地与海洋观测数据。陆地数据源自气象观测资料与固定站位气象船观测资料，已针对站点迁移、仪器变更等非气候误差完成校正处理。所用海洋数据取自《综合海洋-大气数据集》（Comprehensive Ocean-Atmosphere Data Set, COADS）的整编成果，经更新后数据覆盖至1986年；1986年至1991年的补充更新数据，则采用英国气象局（U.K. Meteorological Office）生成的半球海表温度估算值。每条记录包含年份信息与六项年温度距平估算值：分别对应全球、北半球、南半球的温度距平各一项，另外两项为修正厄尔尼诺/南方涛动（El Niño/Southern Oscillation, ENSO）事件影响后的温度距平估算值。该数据集仅包含1个大小为13 kB的数据文件。如需获取该数据集文件，请点击以下链接跳转至CDIAC数据转换网站：http://cdiac.ess-dive.lbl.gov/ndps/ndp022.html
