Sea Surface Temperature and Sea Level From Eastern Pacific
GOES Stations

MARCH 2009
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 and sea level continue near or below normal, not changing
much since December 2008. Intraseasonal fluctuations are evident
in the north but not in Callao.
