Global Sea Surface Temperatures from Japan Meteorological Agency

This dataset contains monthly mean analyzed sea surface temperatures (SSTs) from January 1946 to the latest month for each two degree latitudinal and longitudinal squares over the global ocean between 80S and 80N. The monthly mean SSTs are analyzed at the Oceanographical Division of the JMA based on in situ SST data compiled by the JMA for a period from 1961 to the latest month. The Compressed Marine Reports of the Comprehensive Ocean-Atmosphere Data Set (COADS) compiled by the National Oceanic and Atmospheric Administration of the United States of America are also used in a period from 1946 to 1986. Monthly normals and standard deviations for a thirty-year period from 1961 to 1990 are also available in this directory. They are calculated for the squares which have 5 or more monthly SSTs during the thirty-year period.
