Equation

As printed (Table 11 (W=aD^bH^c))

Above ground 0.055 2.450 0.105 0.983

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

Aboveground biomass = 0.055 * D^2.45 * H^0.105
D
Diameter at breast height (1.3 m), cm
H
Total tree height, m

W = dry weight in kg (Table 7 in kg), D = DBH in cm, H = tree height in m. The paper prints no correction factor, so none is applied. Above ground = stem + branch + foliage (Table 7). DBH 5.9-38.7 cm and height 6.6-26.6 m are the min and max of the per-site ranges in Table 6 (Suwon, Jangseong, Gangjin; ages 8-34 years).
