ABSTRACT
This practice aims to help the reader understand the convergence and efficiency of semi-analytic spin-up (SASU) for different carbon cycle representations in a model. By conducting the TECO spin-up using native dynamics (ND) and the SASU methods, we explore the convergence of different spin-up approaches, and the spin-up efficiency under different carbon input and soil turnover rates. Under weak nonlinear parameterization that assumes carbon input and soil turnover rates are functions of carbon pool sizes, the convergence of two approaches is verified and the spin-up efficiencies are compared.
