Calculate D0
Description
This function calculates the free-air diffusion coefficients
of different gases for a given temperature and pressure.
Usage
D0_massman(gas, t, p)
Arguments
gas
(character) One of "CO2","CH4","N2O","O2","N2"
t
(numeric) temperature in °C
p
(numeric) pressure in hpa
Value
A numeric vector of D0 in m^2/s
