nqfe/WeatherCalcv1.2.3

Dies ist eine Klassenbibliothek, die im Rahmen der FIA Ausbildung entstand.

Diese Klassenbibliothek dient der Ermittlung von:

• Taupunkt
• Hitzeindex
• Windchill
• Wolkenuntergrenze

---

A class library that was created as part of the FIA ​​training.

This class library computes

• Dew point
• Heat Index
• Windchill
• Cloud base
