GOES Stations

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.

SST and sea levels in the eastern Pacific have been fluctuating wildly back and forth
throughout the first months of 2008, reflecting a higher than normal amount of intraseasonal
variability. Values are currently slightly above normal and the fluctuations appear to be
moderating. The indications are consistent with the east Pacific being in a transition
(neutral) phase over the next few months of the austral winter.
