R

• Running mean

S

• Sulphur Dioxide (SO₂)
  Sulphur dioxide is a corrosive acid gas which combines with water vapour in the atmosphere to produce acid rain. Both wet and dry deposition have been implicated in the damage and destruction of vegetation and in the degradation of soils, building materials and watercourses. SO2 in ambient air is also associated with asthma and chronic bronchitis.

• Trajectory Model

V

• Volatile organic compounds (VOCs)

Z

• Zones and Agglomerations
