Climate data rescue 6: Annales du Service météorologique de l'Indochine (ASMI)

Contents of the ASMI The Annales du Service Météorologique de l'Indochine is the third main journal of the French Indochinese Meteorological Service after the Bulletin Mensuel des Observations and the Bulletin Pluviométrique. The complete collection constitutes a set of 13 volumes published from 1930 to 1942 that is fully available in the National archives of Vietnam, Centre n°1, Hanoi and also in Météo France Trappes centre. The first year of edition (1930) published the data of 1928, and the last year of edition (1942) the ones of 1940. The first volume of 1930 also published the monthly averages of the period 1906-1928. The data of this period have of very high interest, since they are the most reliable data we have for this early period. Hence climate historians can consider this period 1906-1928 in the ASMI as a period of reference with reliable observations to observe the climate change in this part of the world in one century. The Annals are divided into 4 main parts: Climatology (that consists, each year, in a description of the network stations, and an overview of the year's weather in each country of the French Indochinese Union) Meteorological data from the Phu Liên central Observatory Meteorological data from the network stations Rainfall data The first part describes the station networks and equipment, giving a general description of the year's weather in the various countries of the Indochinese Union, reviewing the main data (temperature, rainfall, typhoons), and describing the influence of meteorological and climatic factors on indigenous agriculture and European agriculture in each country of the Union. The text contains numerous tables of important data, including the approximate geographical coordinates of all the weather, climate and rainfall stations in the network. The text also contains numerous maps of the network of different types of stations, as well as hypsometric maps. The second part, although entitled ‘daily observations’, actually gives the monthly averages of these daily data. The second part contains the following tables (the semicolon separations indicate the columns of data, the rows being the 12 months of the year) Contents of the dataset The present dataset contains the full 4 parts of the 13 volumes. Each year is divided into 4 files (pdf) corresponding to each part, so as to make it easier for users to access the part of interest to them. Meteorological data coverage 1928-1940
