Through
cooperative arrangements with South American institutions, the TOGA
program has maintained a network of nine tide stations and four
meteorological stations in Ecuador, Peru and Chile since the mid
1980's. The stations are maintained by NOAA/AOML and the University of
Hawaii. The hourly data are transmitted to down-link stations via the
GOES satellite in real time and processed. The five-day averages
(pentads) at critical stations give us an effective means of monitoring
coastal conditions with good time resolution and compact data volume.

The sequence of warmings and sea level rise associated with
the current El Niño has been geographically incoherent along
the Pacific coast of South America in 2009. However, with the exception
of relatively high sea levels in the Galapagos, the coastal stations are
presently quiescent and do not reflect the moderate SST anomalies being
reported in the central equatorial Pacific.
