abstract = "Leaf area index (LAI) and species composition are two ecological parameters that influence atmosphere-biosphere exchange of CO2 and which can be estimated from remote sensing techniques. A process model of biosphere-atmosphere CO2 exchange was used to examine the importance of LAI and species composition when estimating canopy CO2 assimilation in 21 black spruce, white spruce, quaking aspen, paper birch, and balsam poplar forests near Fairbanks, Alaska. Model sensitivity analyses showed that LAI was the single most important parameter determining canopy assimilation. The sensitivity of canopy assimilation to species-dependent physiology was greater between life-forms than within life-forms. These analyses show that canopy assimilation in the boreal forests near Fairbanks is very sensitive to the specification of LAI and physiological differences between coniferous and deciduous trees.",
