Rainfall on Indian Ocean coral islands

Records are presented in this paper for 21 Indian Ocean coral island stations. These are listed, with period of record, mean annual rainfall over this period, and variability, in Table 1. The standard deviation of annual rainfalls is calculated for those stations with a period of record greater than ten years, and variability is given by 100 u/X. The data used are derived from a variety of sources. Records for Cargados Carajos, Agalega, Salomon, Peros Banhos and Diego Garcia are published by the Mauritius Department of Meteorology in the monthly Results of Magnetical and Meteorological Observations from the Royal Alfred observatory (up to 1950) and in the monthly Meteorological Observations and Climatological Summaries (1951-). Records for Amini Divi, Androth and Agathi, in the Laccadive Islands, while not included in monthly rainfall of India, have been made available by the Meteorological Department, Government of India, at Poona. The Meteorological Department, Bracknell, England, has provided published and unpublished records for Christmas Island, Cocos Keeling, Minicoy and Tromelin. Many shorter records have been abstracted during visits to Indian Ocean islands, mostly from records in the Department of Meteorology, Mahe, Seychelles (Aldabra, Alphonse, Bird, Darros, Denis and Poivre). Figures for Addu Atoll were obtained from the Royal Air Force, Gan, and for Assumption from the island Manager.
