Routines to model ocean carbonate system thermodynamics
Synopsis: mocsy is a Fortran 95 package designed to compute all carbonate system variables from total dissolved inorganic carbon (DIC) and total alkalinity, particularly from models. It updates previous OCMIP code, avoids 3 common model approximations, and offers the best-practice constants as well as more recent options. It agrees with CO2SYS within 0.005%.
The mocsy package is described by Orr and Epitalon (2015) and has been compared to other packages that compute marine carbonate chemistry (Orr et al., 2015). More recently, new routinnes were added to propagate uncertainties and compute sensitivities of derived variables to input variables (Orr et al., 2018)
