Spanning 1871-present at monthly timesteps, HadISST provides the longest gridded sea ice data available for both the Arctic and Antarctic. It is a 1° x 1° spatially infilled data set that is It is intended as a consistent analyses for input into SST analyses or as boundary conditions for models. Version 1.1 is the currently available data set and is the one described here. HadISST combines data from historical ice charts from shipping, expeditions and other activities, passive microwave satellite retrievals (primarily the NASA Goddard NASA Team data set), and NCEP operational ice analyses (also based on NASA Team and NASA Team 2 algorithms). A major update of HadISST is planned and this page will be updated when pertinent information is available. The Climate Data Guide will have a separate page discussing the SST portion of HadISST.

Annual Antarctic sea ice extent for 1871-2011 from the HadiSST 1.1 data set. 1871-1939 and 1947-1962 are covered by two climatologies. National Ice Center Charts were used for 1973-1978. Passive microwave satellite data begin in 1978. See Rayner et al (2003). Even during this period, there are discontinuities. In particular, SSMI degraded in early 2009 and NCEP switched to AMSR-E, resulting in spuriously high values for 2009-2011 (see Screen, 2011). (Figure by D. Schneider, NCAR). |
