Arguments

hum_method

Method for humidity input: 1 = relative humidity ( 2 = wet bulb temperature (degC or K) 3 = dew point temperature (degC or K) 4 = specific humidity (kg/kg)

hum

Humidity input (depends on method)

airp

Air pressure (Pa)

tw

Sea surface (water) temperature (degC or K)

ta

Air temperature (degC or K)

rgas

Gas constant for dry air (default 287.05 J/kg/K)

kelvin

Value to convert degC to K (default 273.15)

const06

Constant for specific humidity conversion (default 0.62198)

Value
