NMC Monthly Mean Sea Surface Temperatures (SST) from JCOMM Products Bulletin at LDEO/IRI Climate Data LibraryEntry ID: LDEO_IGOSS_NMC_MONTHLYSST
Abstract: The monthly optimum interpolation (OI) fields are derived by a linear
interpolation of the weekly OI fields to daily fields then averaging
the daily values over a month. The monthly fields are in the same
format and spatial resolution as the weekly fields.
The OI sea surface temperature (SST) analysis is produced weekly on a
one-degree grid. The analysis uses in situ and satellite SST's plus
... SST's simulated by sea-ice cover. Before the analysis is computed, the
satellite data is adjusted for biases using the method of Reynolds
(1988) and Reynolds and Marsico (1993). A description of the OI
analysis can be found in Reynolds and Smith (1994). The bias
correction improves the large scale accuracy of the OI. Examples of
the effect of recent corrections is given by Reynolds (1993).
For the more recent period, 1990-present, the in situ data were
obtained from radio messages carried on the Global Telecommunication
System. The satellite observations were obtained from operational data
produced by the National Environmental Satellite, Data and Information
During the period 1981-1989, the in situ data were obtained from the
Comprehensive Ocean Atmosphere Data Set (COADS) for the 1980s. These
data (see Slutz, et al., 1985, and Woodruff, et al., 1993) consist of
logbook and radio reports. The satellite data were obtained from
analyses of NESDIS data produced at the University of Miami's
Rosentiel School of Marine and Atmospheric Sciences.
The OI analysis is done over all ocean areas. There is no analysis
over land. The land values are filled by a Cressman interpolation to
produce a complete grid for possible interpolation.
