National Meteorological Service of Mexico (SMN) is the federal agency responsible for meteorological observations, weather forecasting, climatological services, and issuing hydrometeorological warnings across Mexico. Founded in the 19th century, the agency operates within the framework of national institutions and collaborates with regional, continental, and global organizations to support aviation, agriculture, civil protection, and maritime activities. Its work links historical figures, scientific centers, and international protocols that shape contemporary meteorology.

History

The origins of modern meteorological services in Mexico trace to initiatives during the presidency of Porfirio Díaz and scientific figures such as Ernesto García (historical scholars associate early observations with military and naval interests), with institutionalization influenced by developments at the Smithsonian Institution, the Royal Observatory, Greenwich, and the Bureau of Meteorology (Australia). During the 20th century, the service interacted with agencies including United States Weather Bureau, Servicio Meteorológico Nacional (Spain), and the International Meteorological Organization before Mexico became a founding member of the World Meteorological Organization. Major events such as the 1910 Mexican Revolution, the Hurricane Janet (1955), and the establishment of the Comisión Nacional del Agua reshaped priorities, leading to expansion of synoptic networks and specialized centers akin to the National Oceanic and Atmospheric Administration, Météo-France, and the Japan Meteorological Agency. Scientific contributions were influenced by collaborations with universities like the National Autonomous University of Mexico, research institutes such as the Centro de Investigación Científica y de Educación Superior de Ensenada, and international programs including the Global Atmosphere Watch.

Organization and Governance

SMN functions under the umbrella of the Comisión Nacional del Agua and follows legal frameworks enacted by the Constitution of Mexico and statutory instruments tied to national water and natural hazard management, reflecting policy dialogues with ministries such as the Secretaría de Medio Ambiente y Recursos Naturales and the Secretaría de Comunicaciones y Transportes. Its governance model mirrors structures found in the European Centre for Medium-Range Weather Forecasts, the National Weather Service (United States), and the Environment Agency (United Kingdom), with directorates responsible for observation, forecasting, climatology, and international affairs. Oversight involves coordination with state agencies like the Protección Civil (Mexico), regional governments of Jalisco, Nuevo León, and Veracruz, and parliamentary committees in the Mexican Congress. The SMN also engages advisory boards comprising representatives from institutions including the Mexican Academy of Sciences, the Academia Mexicana de Ciencias, and academic partners like Instituto Politécnico Nacional.

Responsibilities and Services

SMN provides operational services across aviation, maritime, agricultural, and public safety sectors, aligning with standards from the International Civil Aviation Organization, the International Maritime Organization, and the World Health Organization for heat warnings and vector-borne disease risk. It supplies specialized forecasts for airports managed by Aeropuertos y Servicios Auxiliares and airlines such as Aeroméxico, issues marine forecasts relevant to ports like Veracruz Port and Manzanillo, and supports sectors including the Secretaría de Agricultura y Desarrollo Rural and the Comisión Nacional Forestal for wildfire risk. The agency delivers climatological normals used by the Banco de México and development planners in Secretaría de Desarrollo Agrario, Territorial y Urbano, issues hydrometeorological bulletins for river basins overseen by the National Water Commission, and maintains data archives consulted by organizations such as the Intergovernmental Panel on Climate Change.

Observational Network and Technologies

SMN operates an extensive observational network composed of surface synoptic stations, automated weather stations, radiosondes, radar systems, and satellite reception facilities interfacing with platforms like GOES and Meteosat. Its radar infrastructure is comparable to networks run by Météo-France and Environment and Climate Change Canada, and it maintains coastal tide gauges coordinated with the IOC and regional centers such as the Centro de Investigación en Ciencias del Mar y Limnología. Observations feed into data systems compatible with Global Telecommunication System protocols and ingest model initializations used by centers such as the ECMWF, the National Centers for Environmental Prediction, and the Met Office. SMN leverages technologies including Doppler radar, microwave radiometry, GNSS meteorology, and remote sensing products developed by institutions like NASA and the European Space Agency.

Forecasting, Research, and Climate Monitoring

Forecasting operations produce short-, medium-, and long-range products using numerical weather prediction systems, ensemble techniques, and downscaling methods informed by research from universities and institutes such as the Centro de Ciencias de la Atmósfera (UNAM), the Instituto de Geofísica (UNAM), and the CICESE. SMN contributes observational datasets and analyses to international assessments by the Intergovernmental Panel on Climate Change, participates in research programs like the World Climate Research Programme and the Global Energy and Water Exchanges Project, and collaborates with modeling centers including CNRM and NOAA/ESRL. Climate monitoring includes production of monthly and seasonal outlooks, monitoring of phenomena such as El Niño–Southern Oscillation, Pacific Decadal Oscillation, and links to paleoclimate research involving institutions like the Smithsonian Tropical Research Institute.

Public Warnings and Emergency Preparedness

SMN issues watches, warnings, and alerts coordinated with civil protection authorities such as Protección Civil (Mexico), state emergency services, the Secretariado de la Defensa Nacional, and municipal responders, following frameworks similar to FEMA and Emergency Management Australia. Warning products target hazards including tropical cyclones (season coordinated with National Hurricane Center), severe convective storms, floods, droughts, heat waves, and frost, and are disseminated through media partners like Televisa, TV Azteca, national broadcasters, and social media platforms. Preparedness activities include public campaigns coordinated with the Red Cross (Mexico), humanitarian organizations such as Médecins Sans Frontières, and disaster risk reduction programs tied to the Sendai Framework for Disaster Risk Reduction.

International Cooperation and Data Sharing

SMN actively exchanges data with the World Meteorological Organization network, contributes to the Global Climate Observing System, and participates in bilateral agreements with agencies including the National Weather Service (United States), Environment and Climate Change Canada, Servicio Meteorológico Nacional (Spain), and Météo-France. It supports regional initiatives in the Americas, cooperating within organizations such as the Pan American Health Organization and the Organization of American States, and provides datasets to global centers including the European Centre for Medium-Range Weather Forecasts and NOAA. Data-sharing arrangements facilitate research collaborations with universities like Harvard University, Massachusetts Institute of Technology, University of Oxford, and regional research entities such as Centro de Investigación en Ciencias de la Atmósfera (UNAM). These partnerships enable participation in international field campaigns, capacity-building programs funded by entities like the World Bank and the Inter-American Development Bank, and standardized data exchange under the Global Telecommunication System.
