Unisys SST Anomaly Maps Update

Unisys has determined the cause of the SST anomaly charts showing rapid cooling since September. Our system was using a very limited dataset consisting of SST grids produced since only May 2014. This limited reference data caused the anomaly maps to produce results showing rapid changes amplified as the Northern Hemisphere transitioned into Fall. We have since copied over the grids for a larger reference dataset.


We have also modified the Unisys SST anomaly color enhancement and color bar with a new enhancement and displaying anomalies from -10 deg C to +10 deg C. The “zero” contour is grayed out for easier identification.
