Equations / Aboveground biomass
Pan moist tropical AGB from DBH, height and wood density (Table 4, model 5)
As printed (Section 3.2, model 14 / Table 4, model 5)
In this library's units, ready to compute (kg)
Aboveground biomass = exp(-2.4733 + 0.2893 * ln(D)^2 - 0.0372 * ln(D)^3 + 0.7415 * ln(D^2 * H) + 0.2843 * ln(rho))D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
rho- Wood density (oven-dry mass / green volume), g/cm³
Best pan moist tropical equation in the paper. Table 4 gives the ln(ρ) coefficient in the footnote (0.2843). Coefficients are used as printed; the paper does not state that the log-scale back-transformation correction factor is included, so none is applied. Reported R² is the adjusted R². Equation chosen from the paper's recommended set (7 of its equations captured).

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%.
