A principal objective is to improve calibration of the NASA-CASA productivity andsoil biogeochemistry modeling and subsequently evaluate and refine a series of regionalmodel simulation runs for transformed forest ecosystems. We have implemented theaboveground biomass accumulation (ABA) rate model of Zarin et al. (2001) on the CASA 8-kmregional grid as an initial representation of potential secondary forest regrowth for the LegalAmazon. Our next objective is to evaluate the NASA-CASA model predicted ABA rates overseveral forest clearing and regrowth cycles w ith simulated nitrogen (loss) limitations onsecondary forest NPP patterns.Science Theme:  CD (Carbon Dynamics)Presentation Type:  PosterAbstract ID: 5C lose Windowconverted by Web2PDFConvert.com
