Conclusions:
o HTAPv2.2 provides detailed regional estimates of SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, BC and OC for 2008 and 2010 in monthly 0.1°x0.1° maps ! accounting for the fine spatial resolution and the regional expert information on implemented technologies and end-of-pipe measures
o EDGARv4.3 provides insight on potentially assumed technologies/ emission factors/ end-of-pipe abatement implementation ! reveals differences with EMEP/EEA default emission factors
o The EDGARv4.3 activity data provide temporal trends 1970-2010 (PEGASOS) ! policy hindcast scenarios to evaluate the climate impact of European air quality legislation over the past 4 decades.
HTAP_v2.2 rationale & compilation
Online: final version HTAP_v2.2 of 18/12/13 on ftp://[email protected] or http://edgar.jrc.ec.europa.eu/htap_v2/index.php?SECURE=123 or ECCAD Used by the TF HTAP modellers community to estimate air pollution impacts Remarks: o Only complete countries/ complete speciation from “official” inventories included. o Sector-specific gapfilling was done occasionally (e.g. EMEP-TNO) o Special allocation of point-sources at borders needed for deriving country totals
(e.g. Power Plants)
HTAPv2.2= harmonised mosaic of official & semi-official 0.1°x0.1° monthly gridmaps, gapfilled for global coverage

Hindcast scenarios for PEGASOS
o Scenario 1 = 2010 reference case; o Scenario 2 = 2010 without end-of-pipe in the energy and transport sector o Scenario 3 = 2010 activity with 1970 emission factors & without end-of-pipe in
