GISS Surface Temperature Analysis (GISTEMP) (NASA)

Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v3 (meteorological stations), ERSST v4 (ocean areas), and SCAR (Antarctic stations), combined as described in our December 2010 publication (Hansen et al. 2010). These updated files incorporate reports for the previous month and also late reports and corrections for earlier months.

News
2015-07-19: Closer inspection showed that there was a bug in the ERSST v4 part of the automated update of the ocean data files. The temperature analysis was repeated based on a separate manual construction of the basic ERSST v4 file (SBBX.ERSSTv4). We'd like to acknowledge and thank Nick Stokes for noticing that there might be a problem with the data made public on 2015-07-15. All data and displays were corrected and replaced on the public site today.
