GODAS Subsurface Temperature Anomaly Animations – January 1979 to December 2009

The NCEP Global Ocean Data Assimilation System (GODAS) Animations webpage allows users to view .gif animations of their various datasets. I have wanted to study three of them but have been frustrated with the load time and with the inability to start and stop the animation or to replay periods that interested me. I discovered the animations at the bottom of the GODAS index webpage here:

And here:

I converted them to a format useable by YouTube.

Pacific Zonal Average Temperature Anomaly Animation

The first is the Pacific Zonal Average Temperature animation, which appears to be the average of the subsurface temperatures of the three longitudes provided in the Pacific Y-Z plots (165E, 140W, 110W).

Global X-Z Temperature Anomaly Animation at the Equator

The second is the animation of subsurface temperatures at the equator to depths of 1000 meters (Global X-Z animation at 0N).

Global X-Z Temperature Anomaly Animation at 8S Latitude

The last is the animation of subsurface temperatures at 8S to depths of 1000 meters (Global X-Z animation at 8S).
