 ^{a}Units for annual gross primary production (GPP), net primary production (NPP), and NPPSAT are in grams of carbon per square meter per year (g C m^{−2} year^{−1}). Units for vegetation C (C_{v}) and soil C (C_{s}) are in grams of carbon per square meter (g C m^{−2}). Units for vegetation N (N_{v}), soil N (N_{s}), and inorganic N (N_{av}) are grams of nitrogen per square meter (g N m^{−2}) Units for annual N uptake by vegetation (NUPTAKE) are in grams of nitrogen per square meter per year (g N m^{−2} year^{−1}).
