Météo-France, as National Meteorological Service, is responsible for preserving the memory of the French climate. Météo-France's Climate Archives hold paper meteorological records collected by the French national meteorlogical services since 1878.
Météo-France's Climate Archives are estimated at 7,5 linear kilometers. These archives are stored at 90 locations in France mainland and overseas territories (French Guyana, French Polynesia, French West Indies, New-Caledonia, Reunion Island, Saint-Pierre Miquelon)
This data covers all the French territories from 1800. Records include terrestrial and upper air data.
Other institutions also keep historical climate data, such as archive institutions (i.e. National, Territorial, Departmental, and local archives), scientific institution archives , local and national libraries, Defence Historical Service, ...
For example, French National Archives (Archives nationales) house 2 linear kilometers of physical meteorological records for the period 1800-1970 in Fontainebleau near Paris. They cover France and former French colonies in Africa and include terrestrial, marine and upper air data. An agreement between Archives nationales and Météo-France scientific research has been signed related to the Climate Data Rescue.
