Equations / Aboveground biomass
Liriodendron tulipifera Above ground W = aD + bD^2 (Table 10)

In this library's units, ready to compute (kg)
Aboveground biomass = -3.49 * D + 0.486 * D^2D- Diameter at breast height (1.3 m), cm
W = dry weight in kg (Table 7 in kg), D = DBH in cm. The paper prints no correction factor, so none is applied. Above ground = stem + branch + foliage (Table 7). Predicts negative biomass below about 12 cm DBH (authors' remark), so the authors prefer the power form. 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).

Shaded: the DBH range the model was fitted on. Other inputs held at the values above.
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 = 15 | 57 | 57 | Computed from the printed form computed from the Table 10 coefficients |
| D = 30 | 332.7 | 332.7 | Computed from the printed form computed from the Table 10 coefficients |
