NCEP Version 2.0 OI Global SST and NCDC Version 4.0 Extended Reconstructed SST Analyses

The NCEP OI is a weekly and monthly 1 degree 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 ERSST Version 4 [http://www1.ncdc.noaa.gov/pub/data/cmb/ersst/v4/] is a monthly 2 degree global analysis for 1854 through a current date. EOF methods are used to create these grids using marine surface data (ICOADS). Various climate indexes (e.g. SOI) are available from the Climate Prediction Center [http://www.cpc.ncep.noaa.gov/data/indices/] Recent weekly OI SST plots and other products are available at NOAA OI SST Analysis page [http://www.emc.ncep.noaa.gov/research/cmb/sst_analysis/] Go to Merged Hadley - OI V2 SST and Sea Ice Concentration dataset [http://cdp.ucar.edu/MergedHadleyOI] for a new surface boundary dataset for uncoupled simulations with the Community Atmosphere Model (CAM).
