The Multi-Scale Ultra-High Resolution (MUR) Sea Surface Temperature (SST) Data Set combines data from the Advanced Very High Resolution Radiometer (AVHRR), Moderate Imaging Spectroradiometer (MODIS) Terra and Aqua, and Advanced Microwave Spectroradiometer-EOS (AMSR-E) instruments in an optimal way to produce 1 km global maps of SST.  Noticeable in the animation from 1 January 2010 to 31 December 2011 are the high energy regions associated with the Western Boundary Currents of the Gulf Stream and the Kuroshio.  Additionally one can see the major upwelling areas of the world's oceans associated with the California, Peruvian/Chilean and South African Coasts.
