Global fields were created using a variety of techniques including EOF reconstruction. These data have been shown to contain good ENSO variability back to the late nineteenth century and benefit from a consistent variation of SST with sea-ice concentration within the marginal ice zone. The sea-ice data contain inhomogeneities, particularly in the Southern Hemisphere, and should not be used for studies of sea ice variability. The HadISST1 data set has been shown to be an improvement upon (and has superseded) the GISST data set.
