Servicio Meteorológico Nacional: A History of Argentina's Weather Service
The Servicio Meteorológico Nacional (SMN) stands as a cornerstone of scientific observation in South America. Established during a period of global expansion in atmospheric science, it has evolved from a small federal office into a decentralized national entity, navigating various administrative shifts while maintaining its commitment to meteorological and geomagnetic research.
The Foundation of Meteorological Science in South America
The organization was founded on October 4, 1872, under Federal Law Nº559 during the presidency of Domingo Faustino Sarmiento. Originally named the Oficina Meteorológica Argentina (OMA), it was led by its first director, Dr. Benjamin Apthorp Gould. This establishment marked a significant milestone, as the OMA was the first meteorological organization in South America and only the third in the world, following the creation of similar bodies in Hungary (1870) and the United States (1871).
Initially, the OMA operated under the Ministry of Justice, Cult and Public Instruction. The agency moved quickly to build its infrastructure, establishing the first national network of meteorological stations and geomagnetic observations—the measurement of the Earth's magnetic field—in 1873.

Early International Integration
Argentina quickly integrated into the global scientific community. Between September 2 and September 16, 1873, the OMA participated in the International Meteorological Congress in Vienna, Austria-Hungary. This congress was pivotal, as it led to the establishment of the International Meteorological Organization. Following this, Argentina expanded its research capabilities, recording the first solar radiation observations in Córdoba in 1874 and initiating the first international exchange of meteorological data with neighboring Chile in 1875.
Administrative Evolution and Name Changes
Over the next several decades, the organization underwent numerous structural changes and renamings to reflect its expanding scope of responsibilities.
- 1898: Federal Law Nº3727 transferred the OMA to the Ministry of Agriculture.
- 1924–1927: The organization was renamed Dirección Meteorológica in June 1924, and later Dirección de Meteorología in September 1927.
- 1935: Under Law Nº12252, the name was expanded to Dirección de Meteorología, Geofísica e Hidrología, reflecting a broader focus on geophysics and hydrology (the study of water movement and distribution).
The modern identity of the organization emerged on May 5, 1945, when Decree Nº10131 officially created the Servicio Meteorológico Nacional (SMN), placing it under the Secretary of Aeronautics. This status was formally codified by the Argentine Congress through Law Nº12945 on January 29, 1947.
Governance and Modernization
The mid-20th century saw the SMN shift between various government ministries. On March 9, 1950, it moved to the Ministerio de Asuntos Técnicos de la Nación, and on January 2, 1951, it became a member of the World Meteorological Organization (WMO). By June 22, 1954, it returned to the Ministry of Agriculture (then known as the Ministerio de Agricultura y Ganadería de la Nación).
From May 7, 1957, until October 1966, the SMN was managed by the Ministry of Aeronautics. However, following the coup by Juan Carlos Onganía, the organization was placed under the direct control of the Argentine Air Force for 40 years.
The transition back to civilian control occurred on January 1, 2007, via Decree Nº1689. Shortly thereafter, Decree Nº1432 established the SMN as a decentralized organization under the Ministry of Defense. This modern status grants the SMN its own legal personality and financial control, allowing it to operate independently in both public and private sectors.
