Standardized Sea Surface Temperature (SST) Anomaly

Data:   Reynolds and Smith Version 2 monthly sea surface temperature (deg. C) on a 1.0 x 1.0 deg. lat/lon grid Base Period for Climatology:  1971-2000 Base Period for Standardization:  Dec 1981-present Data Source: NCEP, Environmental Monitoring Center Description:  Sea surface temperature anomaly divided by the standard deviation for the given month over the base period indicated. Shading and contours start at +/- 1 standard deviation, and contours are drawn at intervals of 0.5 s.d. Positive anomalies are in shades of yellow and orange, negative anomalies are in shades of blue.
