Kaplan Global Sea Level Pressure (SLP) Anomalies from LDEO/IRI Climate Data Library

Abstract: A Reduced Space Optimal Interpolation procedure has been
applied to the global sea level pressure (SLP) record from
the Comprehensive Ocean Atmosphere Data Set (COADS) averaged
on a 4x4 degree grid. The SLP anomalies are with respect to
the climatological annual cycle estimated from COADS data
for the period 1951-1980. The data are presented as a monthly

Additional Kaplan SLP data include:
- Optimal Interpolation 1854-1992
- Projected SLP anomalies based on linear best fit of the
EOF patterns to the data 1854-1992
- Kaplan RF and KF Analysis errors and estimates of SLP 1854-1992
