Monthly mean satellite-derived sea surface temperature SST data have been derived globally using daytime and nighttime AVHRR (Advanced Very High Resolution Radiometer) multi-channel data. From a 12 year data set (1982-1993), valid monthly daytime and nighttime climatologies were created using an eight year subset (1984-1990, 1993). Based on buoy comparisons, four years were omitted due to volcanic aerosol corruption (El Chichon 1982/83, Mt. Pinatubo 1991/92). These resulting monthly climatologies provide SST fields at approximately 1/3rd degree latitude/longitude resolution. Difference fields have been created comparing the new satellite climatology with the older and coarser-resolution climatology constructed from conventional SST data. Regional and zonal climatology differences were also created to highlight the deficiencies, especially in the Southern Hemisphere, in the older climatology believed to result primarily from a lack of buoy/ship (in situ) data. Such comparisons made it clear that the satellite climatology provided a much better product. Ocean current systems, El Nino, La Nina, and other water mass characteristics all appear with better detail and accuracy within the high-resolution satellite climatology.
