Bjerknes was a meterologist who
was willing to take a good, hard look
at oceanographic data
x Oceanography a versatile science How Do We Track El Niño Today?
x in situ (on site) measurements
x Satellite sea surface temperature
x Computer models Autonomous Temperature Line Acquisition System Tropical Ocean Global Atmosphere TAO = Tropical Atmosphere Ocean Global impacts from El Niño
