  1. Spatial, temporal and chemical disaggregation of Lombardy 1997 gas inventory G.Maffeis, M.G. Longoni, E. Bossi g.maffeis@terraria.com Terraria srl. Milan - Italy Under contract with Institute for Environment and Sustainability JRC Ispra G.Maffeis - TerrAria srl

  2. 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: SO2 NOX VOC CH4 CO NH3 G.Maffeis - TerrAria srl

  3. Lombardy Emission Inventory macrosector % contribution G.Maffeis - TerrAria srl

  4. Lombardy Emission Inventory NOX (all macrosectors)ton/year G.Maffeis - TerrAria srl

  5. Spatial disaggregation of areal emission where: ECiM: grid cell emission (macrosector M; cell Ci); S(u,M): landuse profile (use u; macrosector M); EcM: municipality emission (macrosector M; municipality c); AcCi(u): landuse u surface, contained in cell Ci and belonging to municipality c.

  6. Spatial disaggregationCORINE land cover G.Maffeis - TerrAria srl

  7. 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 G.Maffeis - TerrAria srl

  8. 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 G.Maffeis - TerrAria srl

  9. 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 G.Maffeis - TerrAria srl

  10. 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 G.Maffeis - TerrAria srl

  11. Temporal disaggregation of emission (a) • t: time h: hour • d: day m: month • p: pollutant • a(t): activity • M(t): meteorology • E(t): emission • EF(t): emission factor • I(t): indicator E(t) = EF(t) * I(t) EF(t) = f1(h, d, m, p, a(t), M(t)) I(t) = f2(h, d, m, a(t)) E(t) = f3(h, d, m, p, a(t), M(t)) “typicalapproximation”: separation of functionality dependence f3(t) = f31(h) * f32(d) * f33(m) * f34(p) * f35(a) * f36(M) G.Maffeis - TerrAria srl

  12. Temporal disaggregation of emission (b) General formulation (used in this work): where: E{(h, gt, s), i, M, cc}: hourly emission (hour h, day gt, season s, pollutant i, macrosector M, climatic zone cc); PH{(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).

  13. Temporal disaggregationClimatic zones 1 = green: plain; 2 = dark green: hill; 3 = brown: mountain. G.Maffeis - TerrAria srl

  15. Temporal disaggregation:CO daily profile SNAP2 G.Maffeis - TerrAria srl

  16. Temporal disaggregation:CO daily profile SNAP2 G.Maffeis - TerrAria srl

  17. Temporal disaggregation:winter working profile SNAP7 G.Maffeis - TerrAria srl

  18. Temporal disaggregation:CO winter daily profile SNAP7 G.Maffeis - TerrAria srl

  19. VOC speciation (a) Reference: • 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” G. Konig, M. Brunda, H. Puxbaum, C.N. Hewitt, S.C. Duckham and J. Rudolph Atmospheric Environment, 29, 861-874 - 1995 G.Maffeis - TerrAria srl

  20. VOC speciation (b) where: PS(i, M): percentage speciation profile of speciesi, macrosector M; PS(i, M): percentage speciation profile of speciesi, activity a belonging to macrosector M; EVOC(M): VOC yearly macrosector M emission; EVOC(a): VOC yearly activity a emission; A(M): number of activities a belonging to macrosector M.
