Determine Real-time SST
Begin with your TAO Monthly Mean SST map
Draw latitude lines every 5° from 10°N to 10°S (ie Blue lines on the above map)
Draw longitude lines every 10° from 160°E to 100°W
Determine SST value at each intersection, or buoy location
As with all scientific procedures, you may find gaps in the data. Using your best judgment, extend out the isotherms and make your best guess.
