|Characterisation Method Name:|
|H2S impact on NEX|
|Principal Method Name:|
|EPS: equivalency method using SO2 as a reference|
|NEX is Normalised EXtinction of species.|
The characterisation factor is determined by an equivalency method using SO2 as a reference.
It is assumed that almost all hydrogen sulphide is oxidised to SO2 in the atmosphere. Therefore 1 kg of H2S is equal to 1.49 kg SO2.
Calculation of characterisation factor
The characterisation factor for SO2 was estimated in "SO2 impact on NEX" to -2.94E-13 NEX per kg SO2. The characterisation factor for H2S is therefore 1.49*(-2.94E-13 ) = -4.38E-13 NEX per kg SO2 per kg H2S.
