Advancement of carbonaceous pressurized canned products outflow stock from fossil fuel burning at European, National and Regional scales by Bruno GUILLAUME and Cathy Liousse (Laboratoire d\'Aérologie)

Slide 2

Outline 1). To Develop another european discharge stock (EI) for BC and OCp (NEWEUR), to enhance comprehension of the biggest contrasts in the current EI (and there are !) 2). To just relate these distinctions to the source/fuel sorts and emittive districts 3). To think about model/estimations BC focuses acquired with NEWEUR and existing EI independently presented in TM4 model

DERIVING THE EMISSIONS OF BC AND OCp substantial split of advances immature outflow controls semi created Pros 1). « lev.dev. »-subordinate : representing both « TECHNOLOGY » and « TECHNOLOGY USAGE » 2). Decision of EF in light of genuine estimations of EF(BC) and EF(OCp) «  innovation based  » with a substantial assorted qualities of advances Cons 1). A great deal of techno however insufficient estimations 2). Decision of EF(BC) and EF(OCp) in light of EF(PM) and evaluations of submicronic, BC/PM and OCp/PM portions EF not representing standards after 1990 in Cooke et al. (1999) Now revised in Junker and Liousse (2006) Particularly substantial contrasts in Europe (Schaap et al., 2004), an area where emanations are regularly expected to be somewhat controlled [Cooke et al, 1999; Junker&Liousse, 2006] or [Bond et al., 2004] ? Cooke et al, J&L Bond et al Fuel-And action subordinate emanations Large contrasts at worldwide scale

OBJECTIVE HERE : IMPROVING J&L\'s BC AND OCp INVENTORIES IN EUROPE (Guillaume&Liousse, 2006, in prep.) Replacement of « lev.dev. based » approach by « technology-based » approach in Europe, expecting: TECHNOLOGY USAGE less basic parameter in Europe than in creating nations MAJOR CHANGES in EF versus Cooke et al. (1999) in local diesel (- ), trafic diesel (- ), lignite (- ) 3). For different innovations in NEWEUR, EF got from : EF values for REF innovation variations of CO/CO2 generally to REF estimation of CO/CO2 « CO/CO2 method » : CO/CO2, as a marker of ignition fulfillment High effect on EF(BC, OCp) for biofuels (chimneys > stoves), for modern coal,lignite (fbc<pc<grate) BUT Low effect on coal emanations (pc is real supporter) Low effect on street diesel (pass auto ~ trucks ~ transports) High effect on street gas (pass autos < 2-strokes) 4). EF controlled got from: EF uncontrolled abattement components (IIASA) (fuel & tech subordinate) Very huge effect on street diesel (Euro standards) NEWEUR 1). Utilization of IIASA fuel-utilization dataset (Klimont et al., 2002) for a considerable length of time 1990,1995,2000,2005 and 2010 (point by point by controlled/uncontrolled portions) 2). Decision of EF(BC, OCp): for some uncontrolled tech. (REF innovations) EF are taken equivalent to J&L\'s EF for semi-dev nations: i). Δ EF(BC) connected to Δ (CO/CO2): the more finish the burning (low CO/CO2), the lower EF(BC) ii). Δ (BC/OCp) connected to Δ ( CO/CO2): the more finish the ignition, the higher BC/OCp.

USE OF A GLOBAL BC MODEL TO TEST NEWEUR AGAINST EXISTING INVENTORIESs Use is made of TM4-tracer = tracer adaptation of ORISAM-TM4 model ( Guillaume et al., Tellus B,2006): - worldwide tracer model (300x200km determination), - long combinations, - 9 vertical levels (up to 40hPa), dry dep (Ganzeveld, 1997), wet dep: convective downpours (Guelle, 1995)/stratiform downpours (incloud and underneath cloud), BC maturing (Cooke et al., 1999).

CONCLUSIONS AND PERSPECTIVES Combustion chamber (LA, Lannemezan) New measured EF(BC,OCp) soon accessible (Lannemezan, 2007) for coal species (lignite, coal, coke) and peat + further acceptance of the CO/CO2 strategy Irish peat German lignite Uncertainties in European BC outflows produced for the most part by instabilities in Central Europe discharges and owing to coal emanations (residential and mechanical burnings), TM4 recreations show enhanced correlation with NEWEUR in Central Europe (yet absence of information), Regional zooms point to higher territorial uncontrolled divisions of street movement. Requirement for regionalisation of inventories underscored by this study
