The locations of the temperature measurements that were used in the 2023 GISS Surface Temperature Analysis (v4). The data on land comes from the weather stations that make up the Global Historical Climatology Network (GHCN). Over water temperature measurements come from International Comprehensive Ocean-Atmosphere Data Set (ICOADS). This dataset provides surface marine observational records from ships, buoys, and other platform types.
