Measurements at São Tomé in the Gulf of Guinea
In 1989, a tide gauge has been installed by ORSTOM (renamed IRD in 1998) on the São Tomé Island (0°20'14"N 6°43'48"E) in the frame of climate research programs (TOGA, WOCE, CLIVAR). This tide gauge, linked to an Argos system for transmitting data in real time (mean sea level, sea temperature and barometric pressure), is part of the global observing network in the Tropical Atlantic and part of the PIRATA network since 1997. The tide gauge station has been GPS located for the international program GLOSS in December 2002. The tide gauge maintenance is performed under the technological IRD reponsability with the help on-site of the non-governmental organization "MARAPA". Data are processed in LEGOS.
In October 2003, a meteorological station has also been installed at São Tomé in the frame of EGEE/AMMA program. This station is part of the PIRATA network since the "Memorendum of Understanding" signed in February 2009 between the international institutes involved in the PIRATA program.
São Tomé: Meteorological station data
In October 2003, a meteorological station has been installed on the São Tomé Island in the frame of the EGEE/AMMA experiment. Raw data from this station (atmospheric pressure, precipitation, humidity, wind speed, wind direction, solar radiation, air temperature) are available on the following ftp website.
São Tomé: Tide gauge data
Tide gauge data are collected in the Laboratoire d'Etudes en Géophysique et Océanographie Spatiales and available online:
- Real time data: available from the "Tide Gauges Network" website
- Delayed mode data after corrections (from 2000 to 2005)
The instrumental drift has been removed as well as the discontinuities in the timeseries related to the tide gauge site changes. Access data
