EUROPEAN EMISSION DATA WITH HIGH TEMPORAL AND SPATIAL-RESOLUTION

The estimation of acidic deposition strongly depends on the availabili ty of accurate emission data. The atmospheric models, that calculate c oncentrations and depositions of pollutants, need data in a high tempo ral resolution (e.g. daily, 6-hourly or even hourly data). However, al though some progress has been achieved concerning annual emission data for Europe (e.g. CORINAIR 90), only very little information is availa ble about the temporal variation of these emissions during a year. The refore, within the EUROTRAC-GENEMIS project special emphasis was laid on the development of methods to generate emissions with a high tempor al and spatial resolution. As results the temporal and spatial distrib ution of SO2-and NOX-emissions are shown. The results indicate, that t he emissions vary considerably over time and that the use of simple pa tterns for the temporal disaggregation is not sufficient for modelling and assessment of acidic deposition.
