aSource indicates various sources for data required as inputs or produced as outputs by the models.

  • F indicates that field data are available for evaluating spatial data sets or model output
  • X indicates that there is an existing spatially explicit data set available
  • D indicates that a spatial data set will be developed as part of this study
  • M indicates that at least one of the models in this study will produce a spatial data set for this variable
  • F,X and F,D combinations indicate the potential for evaluating data sets with field data
  • F,M combinations indicate the potential for evaluating model output with field data
  • X,M and D,M combinations indicate the potential for evaluating model output in the context of spatial data sets.
