"relative_humidity" responses are almost null.

Hi their,

The "relative_humidity" responses are almost null.
We can get the actual relative_humidity, but it seems that there is no relative_humidity with forecast data.
Can we get all relative_humidity?
If we can do it, we can also add "apparent temperature" with temperature, wind speed, and humidity.

Heyho @kanpyo02,

as you correctly observed, while we have real-world-measured relative_humidity (i.e. the value is not null for most historical and current weather records), it is missing from the forecast data. This is a limitation that we inherit from MOSMIX, the DWD's weather forecast product, which does not include forecasts for relative humidity. The full list of available parameters can be found here.

So there is unfortunately not much we can do about the missing relative humidity forecasts unless we want to completely uproot our data collection and switch to a different forecast source (interestingly, ICON, which is itself one of the sources for MOSMIX, does have relative humidity predictions).

I'm closing this as "upstream issue", but feel free to re-open if you hard-disagree ;) There is an ongoing discussion about apparent temperature in #112.
