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

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 climatology. 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
