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.

SSTs along the Peru coast remain on a cooling trend and have
now reached 2°C below normal. The sea levels in Ecuador also
appear lower, overall, and are punctuated by what appear to
be intraseasonal events.
