Formula used:
Stull's approximation for wet-bulb temperature:
Tw ≈ T × atan(0.151977 × √(RH + 8.313659)) + atan(T + RH) − atan(RH − 1.676331) + 0.00391838 × RH3/2 × atan(0.023101 × RH) − 4.686035
where:
T — dry-bulb air temperature in °C
RH — relative humidity in %, for example 94.2, not 0.942
Tw — wet-bulb temperature in °C
