Sal Island meteorological station
The Sal Island meteorological station is a long-running meteorological observatory on Sal, Cape Verde, providing instrumental observations for aviation, maritime navigation, climate monitoring, and research. The facility contributes to regional networks such as the World Meteorological Organization, the African Centre of Meteorological Applications for Development, the National Oceanic and Atmospheric Administration, and the European Centre for Medium-Range Weather Forecasts while supporting operational partners including the Cape Verde Ports and Airports Authority, the International Civil Aviation Organization, and the United Nations World Meteorological Organization.
The station functions as a synoptic and climatological site recording surface and upper-air data for the tropical eastern North Atlantic, working with the Cape Verde Institute of Meteorology and Geophysics, the Portuguese Meteorological Institute, the Pan American Health Organization, the National Aeronautics and Space Administration, and the International Maritime Organization. It supplies routine observations used by the European Space Agency, the United Kingdom Met Office, the Deutscher Wetterdienst, the French Météo-France, and the Servicio Meteorológico Nacional for forecasting, research, and hazard monitoring. Data from the station feed into reanalysis efforts by the National Centers for Environmental Prediction, the Japan Meteorological Agency, the Copernicus Climate Change Service, the Climate Prediction Center, and numerous university research groups at institutions such as the University of Lisbon, Massachusetts Institute of Technology, and University of Oxford.
Established in the 1930s during the era of the Portuguese Overseas Province of Cabo Verde, the site grew from a windsock and barometer to a staffed observatory linking colonial aviation routes, transatlantic shipping lanes, and wartime convoys associated with events like World War II. Post-independence cooperation involved exchanges with the United States Weather Bureau, the British Royal Air Force, the Instituto de Meteorologia de Portugal, and later framework programs with the European Union and the Food and Agriculture Organization. Modernization phases trace to collaborations with the World Bank, the Global Environment Facility, the African Development Bank, and research projects funded by the National Science Foundation and the European Research Council.
Located near Espargos on Sal Island in the northern Sotavento group of Cape Verde, the station occupies low coastal terrain near Amílcar Cabral International Airport and the Port of Palmeira, embedding it within transportation nodes also served by TAP Air Portugal, Cabo Verde Airlines, and cruise lines. Facilities include instrument shelters, radiosonde launch areas, a communications suite interoperable with the International Civil Aviation Organization, storage for oceanographic drifters used by the Woods Hole Oceanographic Institution, and a coordination office linked to the Instituto Nacional de Meteorologia e Geofísica and the Cape Verdean Ministry of Infrastructure and Spatial Planning. The site has been upgraded through projects involving the European Investment Bank, the United Nations Development Programme, and the African Union.
The observatory maintains surface instruments—anemometers, barometers, thermometers, hygrometers—and upper-air systems such as radiosonde balloons, GPS sondes, and radar profilers used by researchers from the Max Planck Institute for Meteorology, the National Center for Atmospheric Research, and the Scripps Institution of Oceanography. Observational streams include SYNOP reports, METAR/SPECI for aviation, SHIP reports for maritime stakeholders like the International Chamber of Shipping and the International Association of Marine Aids to Navigation and Lighthouse Authorities, and data feeds for satellite calibration with Copernicus Sentinel missions, the NOAA GOES program, and NASA’s Aqua and Terra platforms. Quality control and archiving are coordinated with the World Meteorological Organization’s Global Telecommunication System, the Global Climate Observing System, and regional data centers at the African Centre of Meteorological Applications for Development.
The station documents the arid tropical climate of Sal, recording sea‑surface influenced temperature minima and maxima, prevailing northeast trade winds, Saharan dust intrusions linked to the African Easterly Jet and the Saharan Air Layer, and variability tied to Atlantic hurricanes and the El Niño–Southern Oscillation that concern the National Hurricane Center, the Caribbean Disaster Emergency Management Agency, and the Intergovernmental Panel on Climate Change. Long-term series have supported studies by the Hadley Centre, the International Research Institute for Climate and Society, Columbia University’s Lamont-Doherty Earth Observatory, and the Potsdam Institute for Climate Impact Research on trends in precipitation, evaporation, and extreme wind events.
Research at the site underpins investigations into tropical cyclone genesis, aerosol transport, marine boundary layer dynamics, and renewable energy assessment, attracting collaborations with the European Southern Observatory, the International Atomic Energy Agency for radiometric calibration, the World Bank for climate adaptation planning, and universities such as Stanford University, the University of Cambridge, and the University of Cape Town. Applications extend to aviation safety with ICAO procedures, shipping routing with the International Maritime Organization, public health advisories coordinated with the World Health Organization and the Pan American Health Organization, and solar resource assessments informing projects by the International Renewable Energy Agency and the Global Wind Energy Council.
Operations are managed by the Cape Verde Institute of Meteorology and Geophysics with technical support and training from partners including the World Meteorological Organization, Instituto Português do Mar e da Atmosfera, National Oceanic and Atmospheric Administration, and the Met Office. Staffing comprises meteorologists, technicians, radiosonde launchers, data managers, and liaison officers who engage with the African Development Bank, the European Commission’s Directorate-General for Research and Innovation, airports managed by VINCI Airports, and NGOs involved in climate resilience work. The station participates in capacity-building with universities, research institutes, and intergovernmental organizations to sustain observations critical to regional forecasting and international climate science.
