1       Definition

The set of Environment Data such as: temperature, air pressure, humidity etc.

2       Functional Requirements

  1. Temperature is expressed in degrees Celsius.
  2. Pressure is expressed in millibar.
  3. Air humidity can be:
    1. Relative, i.e., the ratio between the actual amount of moisture and the maximum amount possible at the current temperature and expressed in %.
    2. Absolute, i.e., the actual amount of moisture in the unit volume of air and is expressed in grams per kilogram (g/kg).
  4. Wind speed is expressed in m/s.
