It was founded in 1887 as the "Instituto Central Meteorológico" by Royal Decree of August 12 and it was part of the Directorate-General for Public Instruction of the
Ministry of Development. As stated in the founding Decree, the Institute had to "especially calculate and announce the probable weather to the ports and capitals of the province, without prejudice to the other scientific and practical work entrusted to it." In the democratic period, a new restructuring took place in 1978, when it was renamed the National Institute of Meteorology (INM) and became dependent on the
Ministry of Transport and Communications. The second and last restructuring of the agency happened in 2008, when the National Meteorological Institute was renamed State Meteorological Agency and it assumed all the goods and responsibilities of its predecessors. The presidency's powers were divided in two: the
Secretary of State for Environment was designated ex officio president, with representative and government powers over the AEMET, while the executive powers were entrusted to a new position, the director. == Activities and resources ==
