sw.lapse.rate {oce} | R Documentation |
Compute adiabatic lapse rate
lr <- sw.lapse.rate(ctd) lr <- sw.lapse.rate(S, t=NULL, p=NULL)
ctd |
an object of class "ctd ". |
S |
salinity [PSU] |
t |
in-situ temperature [degC] |
p |
pressure [dbar] |
In the first form, the argument is a ctd
object, from
which the salinity, temperature and pressure values are extracted and
used to for the calculation.
Compute lapse rate using Fofonoff and Millard's (1983) formula.
Lapse rate [degC/m].
