This dataset was originally made available by Royal Botanic Gardens, Kew. The following description is taken from the Kew website: http://www.kew.org/gis/projects/madagascar/geolsimp_meta.html. "This map was digitized from the geology map of Madagascar (BESAIRIE, 1964). The 96 original categories were reclassified into predominant rock types which seem to have an important effect on the vegetation they support. The categories of sedimentary rocks include sandstones, loose (unconsolidated) sands, and two limestone categories of different ages (one of which produces the spectacular "tsingy" areas of jagged, highly eroded limestone pinnacles). A broad category of metamorphic rocks (including granites and migmatites), often covered by thick layers of laterites, covers large areas of the central and eastern areas of the island. Lavas and basalts, and several restricted rock types including quartzites, marbles and ultrabasics are also distinguished." For use in REBIOMA models, this map has been resampled from polygons to 30 arc-second grid.

Madagascar bioclimatic variables from CSIRO (Commonwealth Scientific and Industrial Research Organisation, Australia) in 2080, B2a scenario
ESRI Ascii format
RealMat = Mean annual temperature (°C)
RealMar = Mean annual rainfall (sum of mean monthly rainfall) (mm)
MinTemp = The minimum temperature of the coldest month (°C)
MaxTemp = Maximum temperature of the hottest month (°C)
MinPrec = Minimum precipitation of the driest month (mm)
MaxPrec = Maximum precipitation of the wettest month (mm)
Etptotal = evaportanspiration total for 12 months added together (mm)
Wbyear = Water balance for the year (mm) (wbyear = realmar – etptotal)
Wbpos = Number of months with a positive water balance (integer value between 1 and 12)
