Summary

• During the 1997-1998 El Nino, remotely sensed
  observations have provided a truly unprecedented
  description of the complete life cycle of a major
  El Nino event
• The study of El Nino is inherently
  multi-disciplinary
• Space-based observations of SST, surface winds,
  sea level, precipitation, water vapor, ocean
  color, land vegetation, smoke, and fires are
  yielding a global context to the
  ocean-atmosphere-land interactions of the El Nino
  event of the century
• This suite of observations represents a
  significant complement to the in situ TAO array
  and hence the need for improved integration of
  such remotely-sensed and in situ observations.
• The extent to which the satellite observations
  advance prediction skill is not clear
