Meteorological Office of Chile is the national agency responsible for atmospheric observation, weather forecasting, and climate monitoring across the Chilean territory, from the Atacama Desert to Easter Island and the Patagonia archipelago. Established in the 19th century during the era of scientific modernization under figures linked to the Presidency of José Joaquín Pérez, the office evolved alongside institutions such as the Universidad de Chile, the Chilean Navy, and the Instituto de Fomento Pesquero. Its activities intersect with agencies including the Dirección General de Aeronáutica Civil (Chile), the Ministerio de Defensa Nacional (Chile), and international bodies like the World Meteorological Organization and the Intergovernmental Panel on Climate Change.
The origins trace to 19th‑century initiatives influenced by expeditions of Charles Darwin and mapping efforts like the Chilean land survey associated with the War of the Pacific. Early collaborators included the Instituto Geográfico Militar (Chile) and scientific societies such as the Academia de Ciencias de Chile. During the 20th century, the office professionalized through links with the University of Concepción, the Pontificia Universidad Católica de Chile, and exchanges with the United States Weather Bureau and the Met Office in the United Kingdom. Cold War era partnerships involved the National Oceanic and Atmospheric Administration and the Naval Meteorology and Oceanography Command (US Navy), while the late 20th and early 21st centuries saw integration into multilateral frameworks including the World Climate Research Programme and Group on Earth Observations.
The office operates under the Dirección General de Aeronáutica Civil (Chile) and coordinates with the Ministerio de Obras Públicas (Chile), the Servicio Nacional de Geología y Minería, and the Servicio Nacional de Pesca y Acuicultura. Its organizational units mirror international models such as the National Weather Service (United States) and the Météo‑France directorates: divisions for forecasting, climatology, marine meteorology, aeronautical services, and data management. Leadership appointments have involved figures with ties to the Academia Chilena de Ciencias and exchanges with research centers like the Centro de Estudios Científicos (CECs) and the Centro de Modelamiento Matemático (CMM). Regional offices liaise with provincial authorities in Antofagasta Region, Biobío Region, and Magallanes Region.
The office issues forecasts, warnings, and climatological products supporting sectors such as aviation linked to Aerolíneas Argentinas operations at Comodoro Arturo Merino Benítez International Airport, maritime navigation around Cape Horn and the Strait of Magellan, and emergency management coordinated with the Servicio Nacional de Emergencia (Chile). It contributes to agricultural planning alongside the Ministerio de Agricultura (Chile) and to hydrological forecasting in river basins like the Río Loa and the Río Maule. The office supplies data for scientific assessments by the Intergovernmental Panel on Climate Change and national inventories submitted to the United Nations Framework Convention on Climate Change. Public services include bulletins for tourism in San Pedro de Atacama, ski operations in the Andes, and fisheries in the Chilean Sea.
The observational network combines synoptic stations, upper‑air radiosonde sites, marine buoys, radar installations, and satellite reception facilities interoperable with the Geostationary Operational Environmental Satellite program and the Copernicus Programme. Key sites include observatories in Santiago, high‑altitude platforms in the Andes, coastal stations at Valparaíso and Punta Arenas, and island observatories on Easter Island and the Juan Fernández Islands. The network integrates data streams from international platforms such as Global Climate Observing System, ARGOS, and the Tropical Rainfall Measuring Mission. Collaborations with the Comisión Nacional de Investigación Científica y Tecnológica support instrument calibration and maintenance protocols.
Research efforts link the office with universities and institutes including the Universidad de Chile, Universidad de Santiago de Chile, Pontificia Universidad Católica de Valparaíso, and international centers like the Met Office Hadley Centre and the National Center for Atmospheric Research. Topics include downscaling of global models used by European Centre for Medium-Range Weather Forecasts, climate variability associated with El Niño–Southern Oscillation, glacier mass balance studies connected to Instituto Antártico Chileno, and paleoclimate reconstructions drawing on work at the Museo Nacional de Historia Natural (Chile)]. Modeling programs employ frameworks from the Weather Research and Forecasting Model and data assimilation methods from the Data Assimilation Research Testbed. Applied research supports hazard assessment for events like floods in Chile, landslides in Valdivia, and droughts affecting the Central Valley (Chile).
The office is party to multilateral arrangements with the World Meteorological Organization, bilateral memoranda with agencies such as Servicio Meteorológico Nacional (Argentina), Instituto Português do Mar e da Atmosfera, and technical exchanges with JAXA, NASA, and the European Space Agency. It participates in regional initiatives under the Comunidad Sudamericana de Naciones frameworks and contributes to projects by the Pan American Health Organization examining climate impacts on health. Antarctic research cooperation involves the Council of Managers of National Antarctic Programs and national programs including the Instituto Antártico Chileno.
The office provided vital warnings and post‑event analyses for major episodes including the 1960 Valdivia earthquake tsunamis, the 2010 Chile earthquake, recurring El Niño and La Niña impacts, and record droughts in the early 21st century that affected water resources and hydroelectric generation. It has published climatologies used by the World Bank and the Inter‑American Development Bank for infrastructure planning and contributed datasets to global efforts led by the Global Framework for Climate Services and the International Research Institute for Climate and Society.
