1 Definition
The set of Environment Data such as: temperature, air pressure, humidity etc.
2 Functional Requirements
- Temperature is expressed in degrees Celsius.
- Pressure is expressed in millibar.
- Air humidity can be:
- Relative, i.e., the ratio between the actual amount of moisture and the maximum amount possible at the current temperature and expressed in %.
- Absolute, i.e., the actual amount of moisture in the unit volume of air and is expressed in grams per kilogram (g/kg).
- Wind speed is expressed in m/s.
