UNISYS pulls down map showing dramatic ocean cooling

Thanks for looking into this, Harold.


Talking About the Weather

UNISYS ocean cooling not real As some have jested in the climate blogosphere, UNISYS’ recent SST anomaly map looked like the onset of an ice age. UNISYS has pulled the product down for the time being, citing data processing issues.

Many around the climate blogosphere have noted that UNISYS’ recent sea surface temperature anomalies were showing radically different values from various NOAA products.

I decided to reach out to UNISYS directly to find out what might be behind the discrepancies, mentioning that it was confusing that UNISYS was showing Hudson Bay cold, water off the East Coast of Russia frigid, and most of the Northern Hemisphere dramatically cooler than 6 weeks ago, when NOAA was showing nothing of the kind.

  1. Mr Tisdale I’m seeing a discrepancy between NOAA product temperatures and Argo buoy data. Is this common? NOAA seems to run about 1 degree c. warmer than the buoys.

    Fernando Leanme, I’ve never studied the raw ARGO surface data, so I can offer no insight. Please clarify which datasets you’re examining.


  3. Thanks, Bob, for pointing this out.
    And thanks, Harold Ambler, for the discovery.
