Just for the fun of it, I implemented a very small #Python function that calculates the dew point at a given #temperature and relative #humidity (RH).
Now, I'm kind of lost how to calculate how RH changes with #atmospheric pressure.

```python
import numpy as np

def dew_point(T, RH):
Md_by_Ml = 0.622
K1 = 6.112 # hPa
K2 = 17.62 if T >= 0. else 22.46
K3 = 243.12 if T >= 0. else 272.62 # °C
lnRH = np.log(RH)
q = K2/(K3+T)
tau = K3 * (q*T + lnRH)/(q*K3 - lnRH)

return tau
```

I'm not from the field, so be gentle with me please 🥹
