w2Td {aiRthermo}

Dew point temperature from mixing ratio

Description

This function calculates the dew point temperature from given mixing ratio and pressure, following the APPROXIMATE expression 5.68 in Bohren and Albrech (1998).

Usage

w2Td(P, w, consts = export_constants())

Arguments

P

A vector with pressure values in Pa.

w

A vector with mixing ratio (kg/kg).

consts

The constants defined in aiRthermoConstants data are necessary.

Value

This function returns a vector with the dew point temperature.
