The El Niño/La Niña event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. Changes in the normal height of the ocean's surface were observed by the TOPEX/Poseidon altimeter.

This animation shows El Niño and La Niña from
1997 through 1998. Each frame is a ten-day average of sea
surface height (SSH) anomalies—that is, of differences from
normal SSH values. The area shown in the animation is the
Pacific ocean from -20.5 to +20.5 latitude and +120.5 to +289.5
East longitude.
