Critique and Analyses of the Grassland Ecosystem Model ELM
The grassland ecosystem model ELM is discussed and criticized. The critique is based on the examination of the: (a) degree to which the objectives of the model were realized, (b) appropriateness of representation of selected biological, physical, or chemical processes modeled, (c) apparent adequacy of selected model responses, and (d) extent to which the goals of the modeling effort were realized.
The objective of the modeling activity was to develop a total system model of the biomass dynamics of a grassland that was representative of sites in the US/IBP Grassland Biome network and with which there could be relatively easy interaction. The goals of the modeling effort were to create a model that would serve as a communications device and organizer of information, be useful as a research instrument, and yield results helpful in elucidating biological phenomena in grassland ecosystems.
