2 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl1 Spatial, temporal and chemical disaggregation of Lombardy 1997 gas inventory G.Maffeis, M.G. Longoni, E. Bossi Terraria srl. Milan - Italy Under contract with Institute for Environment and Sustainability JRC Ispra

3 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl2 Lombardy Emission Inventory INEMAR (INventario EMissioni ARia) project earthed by Regione Lombardia; Reference year: 1997; Last update: 2001; Time resolution: year; Spatial resolution: municipality; Pollutant: SO 2 NO X VOC CH 4 CO NH 3

4 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl3 Lombardy Emission Inventory macrosector % contribution

5 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl4 Lombardy Emission Inventory NO X (all macrosectors) ton/year

6 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl5 Spatial disaggregation of areal emission where: E Ci M : grid cell emission (macrosector M; cell Ci); S(u,M): landuse profile (use u; macrosector M); E c M : municipality emission (macrosector M; municipality c); A c Ci (u): landuse u surface, contained in cell Ci and belonging to municipality c.

8 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl7 Spatial disaggregation (a) NOx macrosector 2 (ton/year) DOMAIN: (459; 4.945) UTM Km x and y step: 5000 m x cells: 47 y cells: 45

9 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl8 Spatial disaggregation (b) VOC macrosector 6 (ton/year) DOMAIN: (459; 4.945) UTM Km x and y step: 5000 m x cells: 47 y cells: 45

10 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl9 Spatial disaggregation (c) NOx macrosector 7 (ton/year) DOMAIN: (459; 4.945) UTM Km x and y step: 5000 m x cells: 47 y cells: 45

11 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl10 Spatial disaggregation (d) VOC macrosector 11 (ton/year) DOMAIN: (459; 4.945) UTM Km x and y step: 5000 m x cells: 47 y cells: 45

12 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl11 Temporal disaggregation of emission (a) E(t) = EF(t) * I(t) EF(t) = f 1 (h, d, m, p, a(t), M(t)) I(t) = f 2 (h, d, m, a(t)) E(t) = f 3 (h, d, m, p, a(t), M(t)) typical approximation: separation of functionality dependence f 3 (t) = f 31 (h) * f 32 (d) * f 33 (m) * f 34 (p) * f 35 (a) * f 36 (M) t: timeh: hour d: daym: month p: pollutant a(t): activity M(t): meteorology E(t): emission EF(t): emission factor I(t): indicator

13 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl12 Temporal disaggregation of emission (b) where: E{(h, gt, s), i, M, cc}: hourly emission (hour h, day gt, season s, pollutant i, macrosector M, climatic zone cc); P H {(h, gt, s), i, M, cc}: the 24 hours temporal profile (2376) for the day gt (3), the season s (4), the pollutant i (6), the macrosector M (11) the climatic zone s (3); E{(a, i, M, cc}: yearly emission (year a, pollutant i, macrosector M, climatic zone cc). General formulation (used in this work):

20 1997 Lombardy inventory disaggregationG.Maffeis - TerrAria srl19 VOC speciation (a) Reference: AEAT/ENV/R/0546 Issue 1 AEAT/ENV/R/0546 Issue 1 Speciation of UK emissions of non-methane organic compounds N.R. Passant - February 2002 Relative contribution of oxygenated hydrocarbons to the total biogenic VOC emissions of selected mid-European agricultural and natural plant species Relative contribution of oxygenated hydrocarbons to the total biogenic VOC emissions of selected mid-European agricultural and natural plant species G.
