Update (April 21, 2012): Unisys made the announcement back in September that they were changing color schemes, but they haven’t made the switch. I wonder what happened.
A couple of weeks ago, Unisys announced they are changing the color scaling on their daily Sea Surface Temperature (SST) anomaly maps. Refer to their post New Sea Surface Temp Anomalies Graphic. The following gif animation compares the old and the new presentations:
Old and New Unisys SST Anomaly Maps
Based on user feedback we developed a new version of our Sea Surface Temperature Anomalies plot with a different color scale. We had been asked to modify the color scale to better differentiate between above and below normal temperatures.
Unisys also asked for comments. There’s a link on their blog post linked above. I suggested a band of neutral white at +/- 0.05 deg C.
The new Unisys SST anomaly map looks more like the GlobalSST anomaly maps from the NOAA Coral Reef Watch website:
