mom_eos::calculate_density subroutine subroutine mom_eos::calculate_density::calculate_density_scalar (T, S, pressure, rho, EOS, rho_ref, scale) calculate_density_scalar T T S S pressure pressure rho rho EOS EOS rho_ref rho_ref scale scale Calls the appropriate subroutine to calculate density of sea water for scalar inputs. If rho_ref is present, the anomaly with respect to rho_ref is returned. The pressure and density can be rescaled with the US. If both the US and scale arguments are present the density scaling uses the product of the two scaling factors. t Potential temperature referenced to the surface [degC] s Salinity [ppt] pressure Pressure [Pa] or [R L2 T-2 ~> Pa] rho Density (in-situ if pressure is local) [kg m-3] or [R ~> kg m-3] eos Equation of state structure rho_ref A reference density [kg m-3] scale A multiplicative factor by which to scale density in combination with scaling given by US [various] subroutine subroutine mom_eos::calculate_density::calculate_density_array (T, S, pressure, rho, start, npts, EOS, rho_ref, scale) calculate_density_array T T S S pressure pressure rho rho start start npts npts EOS EOS rho_ref rho_ref scale scale Calls the appropriate subroutine to calculate the density of sea water for 1-D array inputs.
