Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP v4)

Goddard Institute for Space Studies (GISS) Surface Temperature Analysis version 4 (GISTEMP v4) is an estimate of global surface temperature change. Graphs and tables are updated around the middle of every month using current data files from National Oceanic and Atmospheric Administration (NOAA) Global Historical Climatology Network (GHCN) v4 (meteorological stations) and Extended Reconstructed Sea Surface Temperature (ERSST) v5 (ocean areas), combined as described in our publications Hansen et al. (2010) and Lenssen et al. (2019). These updated files incorporate reports for the previous month and also late reports and corrections for earlier months.

戈达德太空研究所（Goddard Institute for Space Studies, GISS）地表温度分析第4版（GISTEMP v4）是一项用于估算全球地表温度变化的数据集。该数据集的图表与表格约于每月中旬完成更新，更新所使用的当前数据文件源自美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的全球历史气候学网络第4版（Global Historical Climatology Network, GHCN v4，用于气象站点数据）以及扩展重建海表温度第5版（Extended Reconstructed Sea Surface Temperature, ERSST v5，用于海洋区域数据），二者的融合方法详见汉森等人（Hansen et al., 2010）与伦森等人（Lenssen et al., 2019）的相关研究。本次更新的数据文件不仅纳入了上月的观测报告，还包含了前期月份的延迟上报数据与修正信息。
