sw.lapse.rate {oce}R Documentation

Seawater lapse rate

Description

Compute adiabatic lapse rate

Usage

sw.lapse.rate(S, t=NULL, p=NULL)

Arguments

S either salinity [PSU] (in which case t and p must be provided) or a ctd object (in which case S, t and p are determined from the object, and must not be provided in the argument list).
t in-situ temperature [degC]
p pressure [dbar]

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.

Value

Lapse rate [degC/m].
