The GISS Surface Temperature Analysis version 4 (GISTEMP v4) is an estimate of global surface temperature change using current data from NOAA GHCN v4 (meteorological stations) and ERSST v5 (ocean areas).

NASA's full dataset of global surface temperatures as well as full details with code of how NASA scientists conducted the analysis, are publicly available from GISS. GISS is a NASA laboratory managed by the Earth Sciences Division of the agency's Goddard Space Flight Center in Greenbelt, Maryland. The laboratory is affiliated with Columbia University's Earth Institute and School of Engineering and Applied Science in New York.

Global Temperature Anomalies for 2025 (no smoothing)

No description available.

2025 global surface air temperature anamalies. In this version, there is no spatial smoothing of the dataset. The map is in a Robinson projection. The colormap is "vik" from Crameri (2018).

Global air surface temperature anomalies for the year 2025 relative to a baseline period of 1951-1980.

2025 Global Temperature Anomalies (smoothed)

No description available.

2025 global surface air temperature anamalies. In this version, the dataset is spatially smoothed. The map is in a Robinson projection. The colormap is "vik" from Crameri (2018).

2025 global surface air temperature anamalies relative to a baseline period of 1951 - 1980.

Global Temperature Anomalies from 1880 - 2025 (no smoothing)

2025 global surface air temperature anamalies. In this version, there is no spatial smoothing of the dataset. There is 12 months of temporal averaging. The time on the timeline cooresponds to the midpoint of the smoothing window. The map is in a Robinson projection. The colormap is "vik" from Crameri (2018).
