This function estimates the dew point temperature (C) using the Magnus-Tetens approximation,
based on the minimum air temperature and relative humidity at that time.
Arguments
- mint
Numeric. Minimum air temperature in degrees Celsius.
- minrh
Numeric. Relative humidity (%) at minimum temperature.
Value
Numeric. Dew point temperature in degrees Celsius.
Details
The dew point temperature is calculated using the following equations:
$$
\gamma = \frac{a \cdot T}{b + T} + \ln\left(\frac{RH}{100}\right)
$$
$$
T_{dew} = \frac{b \cdot \gamma}{a - \gamma}
$$
where \(a = 17.62\) and \(b = 243.12\).
