So2 Layer Height
Measurement Instruments
Measurement Definition: Height of vertically localised sulphur dioxide (SO₂) layers in the atmosphere, such as those in volcanic eruption plumes that may pose hazards to aviation. The altitude of these layers is also important for assessing their potential impact on climate. Measuring Units: m, Uncertainty Units: m.
