Equation
As printed (Table 2, p. 12)
Wt = ΣWi
In this library's units, ready to compute (kg)
Aboveground biomass = (0.00716 * D^2.02253 * H^1.30938) + (0.03088 * D^1.10021 * H^1.09925) + (0.01613 * D^1.90578 * H^0.70112) + (0.03886 * D^1.53515 * H^0.31776)D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
Equation as printed in the Table 2 system for this taxon; d is DBH in cm, h total height in m, output in kg dry mass. R² is the 10-fold cross-validation value. Total AGB is printed as Wt = sum of the four components (stem wood, stem bark, branches, foliage); the expression is that sum of the four printed equations.

On every build, the library's form and the paper's own form (in its units) must both give these values within 1%.
| Inputs | Expected | We get | From |
|---|---|---|---|
| D = 20, H = 12 | 128 | 128 | Computed from the printed form computed from the Table 2 equations (sum of the four components) |
| D = 35, H = 18 | 585 | 585 | Computed from the printed form computed from the Table 2 equations (sum of the four components) |
