Western North Pacific Sea Surface Temperatures from Japan Meteorological Agency

Western North Pacific Sea Surface Temperatures

This directory contains 10-day mean analyzed sea surface temperatures (SSTs)
since January 1950 to the latest 10-day for each one degree latitudinal and
longitudinal square from 100E to 180E between the equator and 60N.

Here, the '10-day' is determined as follows. Three '10-day' analyses are
made in each month, and the first 10-day is from the first to the 10th day
of the month, the second is from 11th to 20th and the third is from 21st
to the last day of the month.

The 10-day 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 10-day. The Compressed Marine Report 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. Since 1998, NOAA/AVHRR data have been also used for the region
from 120E to 160E between 20N and 50N. The NOAA/AVHRR data are received and
processed at the Meteorological Satellite Center of the JMA.

10-day normals and standard deviations for a 30-year period from 1961 to 1990
are also available in this directory. They are calculated for the squares
which have 5 or more than 10-day mean SSTs during the 30-year period.
