swLapseRate: Seawater lapse rate

Description

Compute adiabatic lapse rate

Usage

swLapseRate(salinity, temperature=NULL, pressure=NULL)

Arguments

salinity
either salinity [PSU] (in which case temperature and pressure must be provided) or a ctd object (in which case salinity, temperature and pressure ar
temperature
in-situ temperature [$^\circ$C]
pressure
pressure [dbar]

Value

  • Lapse rate [$deg$C/m].

Details

If the first argument is a ctd object, then salinity, temperature and pressure values are extracted from it, and used for the calculation.

Compute lapse rate using Fofonoff and Millard's (1983) formula.
