Detailed Description:

  • From the NASA webpage: Temperature data is updated "around the middle of every month using current data files from NOAA GHCN v3 (meteorological stations), ERSST v5 (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." Please refer to the NASA webpage for more details, caveats, and products.
