Schedule 4 MEASUREMENTS OF OZONE PRECURSOR SUBSTANCESI1
Northern Ireland
I1
The main objectives of measurements of ozone precursor substances are to analyse any trend in ozone precursors, to check the efficiency of emission reduction strategies, to check the consistency of emissions inventories and to help attribute emission sources to pollution concentration.
An additional aim is to support the understanding of ozone formation and precursor dispersion processes, as well as the application of photochemical models.
