NCEP Version 2.0 OI Global SST and NCDC Version 3.0 Extended Reconstructed SST Analyses

The NCEP OI is a weekly and monthly 1x1 global analysis dataset that is available for November 1981 through a current date. The analyses are determined by blending marine surface observations (ICOADS and others) and satellite AVHRR data using an OI method.

The NCDC V3ERSST is a monthly 2x2 global analysis for 1854 through a current date. EOF methods are used to create these grids using marine surface data (ICOADS).

Various climate indicies (e.g. SOI) are available from the Climate Prediction Center

Recent weekly OI SST plots and other products are available at NOAA OI SST Analysis page
