As printed (Table 2, p. 12)

Wt = ΣWi

In this library's units, ready to compute (kg)

Aboveground biomass = (0.04428 * D^1.8953 * H^0.84674) + (0.00341 * D^1.96215 * H^0.66178) + (0.0051 * D^1.78757 * H^1.12341) + (0.03041 * D^1.78361)
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.
