Abstract

The goal of this study was to evaluate how factorial combinations of two mixing models and two regression approaches (Keeling-OLS, Miller—Tans-OLS, Keeling-GMR, Miller—Tans-GMR) compare in small [CO₂] _range versus large[CO₂] _range regimes, with different combinations of pertinent variables that are realistic for experimental applications in each of the two regimes.
