1   Definition

Weather Data is a set of data that includes

  1. Temperature
  2. Humidity
  3. Air Pressure
  4. Ice conditions
  5. Wind conditions
  6. Condensed water in various states:
    1. gaseous: fog
    2. liquid: rain
    3. frozen: snow, sleet, hail

2   Functional Requirements

  1. Temperature measure in degrees °C
  2. Ice conditions (yes/no)
  3. Wind conditions (Azimuth and velocity measured in m/s)
  4. Density of fog measured in meters of clear visibility
  5. Amount of rain measured in mm/h
  6. Hail measured in mm of hailstone size
  7. Snow measured mm/h
  8. Sleet measured in meters of clear visibility.
