Model description

BIOME4 (Kaplan et al., 2003) is a coupled biogeography and biogeochemistry model which simulates the equilibrium distribution of 28 major potential natural vegetation types (biomes) from latitude (for the calculation of incoming short-wave and photosynthetically active solar radiation), atmospheric CO2 concentration, mean monthly climate (i.e. mean monthly precipitation, temperature, and percent sunshine) and soil physical properties (water holding capacity and percolation rate). Photosynthesis, stomatal behaviour and hydrology are simulated as in BIOME3 (Haxeltine & Prentice, 1996) and the ecosystem dynamics model LPJ (Sitch et al., 2003). BIOME4 implicitly simulates competition between plant functional types (PFTs) as a function of relative net primary productivity (NPP) and uses an optimisation algorithm to calculate the maximum sustainable leaf area (LAI) of each PFT and its associated NPP. Empirical rules are used to classify these outputs and assign biomes based on the identity of the most successful and second-most successful PFT and their sustainable LAI.

BIOME4 successfully reproduces the distribution of potential natural vegetation and associated phenological, hydrological and biogeochemical properties. BIOME4 and earlier members of the BIOME model family have been used previously as diagnostic tools (e.g. Prentice et al., 1993; Harrison et al., 1995; TEMPO, 1996; Kutzbach et al., 1996; Kutzbach et al., 1998; Harrison et al., 1998; Coe & Harrison, 2002; Vavrus & Harrison, 2003), to simulate vegetation patterns consistent with a given climate simulation for comparison with observed palaeovegetation data (e.g. Broström et al., 1998; Jolly et al., 1998; Prentice et al., 1998; Mahowald et al., 1999; Kaplan et al., 2003), and to simulate vegetation-climate feedbacks in the past (de Noblet et al., 1996; Claussen, 1997; Texier et al., 1997; Kubatzki & Claussen, 1998; Braconnot et al., 1999).

If you wish to use BIOME4 in asynchronously-coupled mode to simulate vegetation changes and feedback, please cite Kaplan et al. (2003) as the source of the model. Technical queries about the BIOME4 (and other models in the BIOME family) should be addressed to Colin Prentice. Development of BIOME4 was spearheaded by Jed Kaplan and funded by the Swedish Natural Science Research Council (NFR) and the Max-Planck Institute for Biogeochemistry.
