gsw_latentheat_evap_t

Latent heat of evaporation

Description

Latent heat of evaporation

Usage

gsw_latentheat_evap_t(SA, t)

Arguments

`SA`	Absolute Salinity [ g/kg ]
`t`	in-situ temperature (ITS-90) [ degC ]

Details

The present R function works with a wrapper to a C function contained within the GSW-C system (Version 3.05-4 dated 2017-08-07, available at https://github.com/TEOS-10/GSW-C, as git commit '5b4d959e54031f9e972f3e863f63e67fa4f5bfec'), which stems from the GSW-Fortran system (https://github.com/TEOS-10/GSW-Fortran) which in turn stems from the GSW-Matlab system (https://github.com/TEOS-10/GSW-Matlab).

Value

latent heat of evaporation [ J/kg ]
