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.

At the end of February SSTs and sea levels plunged suddenly
to normal or below normal values. This could signal the end
of the El Niño event in the NINO 1+2 region. SST anomaly maps
of the Pacific are showing that the warm anomalies are mainly
concentrated near the dateline.
