Program Developed for CO2 System Calculations (Program files: CO2SYS_calc_DOS_v1.05; CO2SYS_calc_XLS_v2.3; CO2SYS_calc_MAC_WIN; CO2SYS_calc_MATLAB_v1.1) (NCEI Accession 0164485)

The program CO2SYS performs calculations relating parameters of the carbon dioxide (CO2) system in seawater and freshwater. The program uses two of the four measurable parameters of the CO2 system [total alkalinity (TA), total inorganic CO2 (TCO2), pH, and either fugacity (fCO2) or partial pressure of CO2 (pCO2)] to calculate the other two parameters at a set of input conditions (temperature and pressure) and a set of output conditions chosen by the user. It replaces and extends the programs CO2SYSTM.EXE, FCO2TCO2.EXE, PHTCO2.EXE, and CO2BTCH.EXE, which were released in May 1995. It may be run in single-input mode or batch-input mode and has a variety of options for the various constants and parameters used. An on-screen information section is available that includes documentation on various topics relevant to the program. This program may be run on any 80 x 86 computer equipped with the DOS operating system by simply typing CO2SYS at the prompt after loading the executable file CO2SYS.EXE.

Original version for DOS was written by Lewis and Wallace. This was converted to MATLAB by Denis Pierrot at CIMAS, University of Miami, Miami, Florida. Vectorization, internal refinements and speed improvements were added by Steven van Heuven, University of Groningen, The Netherlands. Although functionality has been added, the output of the function has not changed. All versions of co2sys available at NCEI (CO2SYS_calc_DOS_v1.05; CO2SYS_calc_XLS_v2.3; CO2SYS_calc_MAC_WIN; CO2SYS_calc_MATLAB_v1.1) should yield (near-) identical results when supplied with identical input.
