Nicholson, S.E., A.K. Dezfuli, and D. Klotter, 2012: “A two-century precipitation dataset for the continent of Africa.” Bulletin of the American Meteorological Society, v. 93, pp. 1219–1231, doi: 10.1175/BAMS-D-11-00212.1.
A wealth of historical information on climate and weather exists for the African continent. Documentary information, hydrologic indicators, and rain gauge records have been compiled and combined into a semiquantitative precipitation dataset that extends from 1801 to 1900. That dataset describes “wetness” for 90 regions of Africa, using a seven-category index. A regional gauge dataset for 1901–2000 has been converted to the seven-class system, extending coverage to two centuries. These datasets are available through the Paleoclimate Data Center.
