Vapour-pressure deficit (Pa)

Vapour-pressure deficit (Pa)

vpd(Tc0, Tc1, MI, ca0, ca1, scale_factor = 101.325 * 10^-3)

Arguments

Tc0

Numeric vector with modern mean growing season temperature values (°C).

Tc1

Numeric vector with palaeo (past) mean growing season temperature values (°C).

MI

Numeric vector with reconstructed moisture index values (-).

ca0

Numeric vector with modern ('recent') CO2 partial pressures (umol/mol).

ca1

Numeric vector with palaeo (past) CO2 partial pressures (umol/mol).

scale_factor

Scale factor to transform the output, default = 101.325 Pa/ppm at standard sea level pressure.

Value

Numeric vector with vapour-pressure deficit values.
