Land use data has been obtained from , where the surface of the earth is divided into 44 different land ecosystem complexes of size each. Although the resolution needed was much higher than the resolution given, no attempt has been made to add more detailed land use data by way of manual editing, use of digitized cartographic data, etc. A filter was used to translate the ecosystem complexes given into the twelve different land use categories needed by the meteorological preprocessor (see Table 6.1, p. ). Again, no attempt has been made to extrapolate the data to the time period of interest.
