Tracking El Niño Site Map ENSO Surface Data Comparison
back to article

This panel maps the El Niño signal in animations of surface data from three satellite instruments: at the top is wind speed from NSCAT, in the middle is sea surface height from TOPEX/Poseidon, and on the bottom is temperature from AVHRR. The ability to see at a glance if a pattern of interaction exists between the three maps is just as important as the data itself. This still is from May 1, 1997.
