    Multiscale analysis of global variation in tree allometric relationships: parameter sets for global vegetation models by Ian Grant, Wenge Ni-Meister, Nancy Y Kiang

    Published 2025-01-01
    “…Global models of vegetation dynamics and remote sensing data products require allometric relationships governing trees’ size and shape to predict such quantities as vegetation spatial structure and biomass. However, empirical variation in allometric relationships poses a challenge for global scale models that rely on limited classifications of plant functional types (PFTs), as site-derived parameters often fail to apply appropriately out of sample. …”
