Calculate water vapor pressure — calc_vapor

Calculates the vapor pressure of freshwater or seawater in atmospheres.

Usage

calc_vapor_press(temp_water = 25, salinity = 0, method = "Dickson2007")

Arguments

temp_water: Numeric vector. Water temperature in degrees Celsius. Defaults to 25.
salinity: Numeric vector. Salinity in practical salinity units. Defaults to freshwater (0).
method: Character string. Calculation method. Use "Dickson2007" for seawater and "MIMSY" for freshwater. Defaults to "Dickson2007".

Value

Numeric vector of vapor pressure in atm.

Details

"Dickson2007" follows the ocean CO2 best-practices guide and includes a salinity correction. "MIMSY" uses the Antoine equation for freshwater.
