Convert between stomatal conductances to water vapour and carbon dioxide.
Usage
gs_c_from_gs_w(gs_w, temperature = 21)
gs_w_from_gs_c(gs_c, temperature = 21)
gs_vol2mol(gs, temperature = 21, pressure = 101300)
gs_mol2vol(gs_c, temperature = 21, pressure = 101300)
Arguments
- gs_w, gs_c, gs
numeric Stomatal conductance to water vapour and carbon
dioxide [\(m^2\,s^{-1}\)].
- temperature
numeric Temperature [\(^{\circ}C\)], in the range -7
to 47 \(^{\circ}C\).
- pressure
numeric Pressure of the gas, e.g., atmospheric pressure [Pa].
Value
A numeric vector of stomatal conductance values expressed as
\(m^2\,s^{-1}\).
Details
These conversions are based on the diffusion coefficients, both of
which are looked up based on the temperature.
