where N is the stand density (ha^{1}); hdom is the dominant height (m); t is the stand age (years); dg is the quadratic mean dbh (cm); cop is a dummy variable for coppice, assuming the value 0 for planted stands and 1 for coppice stands; h is the total tree height of the average tree (m); h_{st} is the stump height considered 0.15 m; h_{c} is the tree height up to the base of the crown (m); h_{i} is the top height (m); d_{i} is a top diameter (cm); w_{i di} is the biomass of the component below diameter d_{i} (Mg ha^{1}) and where i represents: w for wood, b for bark, br for branches and l for leaves; wa_{di} is the aboveground biomass below a top diameter d_{i}.
