The SIM-BIM model presented is a combination of the daily-step enzyme activity model SIM (Lehning et al. 2001) and the biochemical process-model of isoprenoid emission BIM (Zimmer et al. 2000, Grote et al. 2006). The combined model has been successfully applied to simulate isoprene emission from Sessile oak (Zimmer et al., 2003) and Holm oak (Grote et al. 2006, Grote 2007).
The stand-alone version of SIM-BIM needs the combination with a phenological model to indicate the state of foliage development and a photosynthesis model that supplies the substrates for isoprenoid formation. For canopy scale analysis and consideration of indirect environmental impacts (such as drought), the model has been integrated into the plant growth model PSIM (Grote 2007).
