Here, we show how terrestrial laser scanning (TLS) methods have developed to the point where they can be routinely deployed to measure tree structure of tropical forest trees accurately and non-destructively ; this is not currently possible any other way. We present results from TLS field campaigns across the tropics, including Africa, S. America and Australia. We use the TLS measurements to derive estimates of tree volume and, combined with wood density estimates, AGB. We show that these estimates agree to within a few % of destructively measured values . We also show that TLS measurements can capture the size and structure of all trees within measured plots, resulting in size estimates that are significantly different from existing allometries. We discuss the potential for (and implications of) including TLS-derived measurements into tropical forest allometries, for improving estimates of C stocks, particularly for large trees, and particularly from forthcoming EO missions that will depend on tropical forest allometry.
