Compilation of national modelled air quality maps Peter de smet, Frank de Leeuw (RIVM,NL) Jan horálek, Pavel Kurfürst (CHMI, CZ) ETC/ACM Contact: Peter.de.smet@rivm.nl Report: ttp://acm.eionet.europa.eu/reports/ETCACM_TP_2013_3_compAQmodelmaps

Compilation of national modelled AQ maps Original idea European air quality maps ETC: spatial interpolated maps (Airbase stations) Models (e.g. EMEP, Lotos-Euros) What if national modelling results as input? Which consistencies & discrepancies between countries products above Taste of comparability of national modelling results. Could composite maps perhaps replace all other map products? 12 april 2013 Compilation of national modelled AQ maps

Compilation of national modelled AQ maps Phase 1 – 1st inventory Check AQ Questionnaire on model use (EU27, EFTA) Latest AQQ 2010: 5x PM10 - 12x Benzene (in 2011) A generic email to all AQQ contactpersons  11 response (Table 1: model data/poll./cntry) Too little to prepare a European composite map …. we had little expectation on some outcome…but: 12 april 2013 Compilation of national modelled AQ maps

Compilation of national modelled AQ maps Phase 2 - 2nd inventory Systematic internet search (May 2012) on national & sub-national modelling activities public information Extension EEA32 Member Countries EEA’s 7 Cooperating Countries (Annex 1: search results/country) Had to narrow down to: PM10, NO2, SO2 Most countries model these pollutants AQD-wise Our limited time and resources 12 april 2013 Compilation of national modelled AQ maps

Based on search results further focus for data request: PM10, NO2, SO2 Annual averages most countries simple indicator 2010 If modelling ongoing -> reasonable change data available Recent year -> actuality of info & model (version) used Reports and data readily available (‘from-the-shelf’ / ‘fresh-in-the-mind’  little effort to contribute) Larger change on comparability with other map products (Match with phase 1 inventory) 12 april 2013 Compilation of national modelled AQ maps

By dedicated & personalised email: Refering to exact and relevant info found on internet Request for data + some model info + ref. to MDS Indicate we will do: no model benchmarking ! no performance judgement ! Only visual interpretation of composite maps To: All contacts/addresses found on web sites AQQ contact persons (+ EoI contacts; at cases data supplier) total: 32 countries (1 ~ 6 addresses/country) (Annex 2: email example) (Annex3: contacted persons) 12 april 2013 Compilation of national modelled AQ maps

Compilation of national modelled AQ maps Responses: Enthusiasm (overwhelming to ETC; involved lot of handling) Intensive & constructive communication From 31 countries 19 with modelling data 15 national for annual national AQ assessments 4 sub-national (Italy also national – arrived too late for composite map) 12 no data (yet) Many indicated working on implementation regular modelling Few months to 2 years time(Nov 2012) (Table 2, Annex 4: respondents & some details) (Annex 5: provided modelling info and MDS reference) 12 april 2013 Compilation of national modelled AQ maps

Composite maps processing: Conversion of (sub)national projections into EEA’s ETRS_1989_LAEA_52N_10E Eliminating non-matching bordering areas Coping with resolution changes at conversion (Section 6.3) Aim: Keep original spatial resolution and orientation Keeps info content of data as original as possible Identify easier differences between nations/models Visual analysis on discrepancies between countries 12 april 2013 Compilation of national modelled AQ maps

Findings from inventory Positive + enthusiastic attitude to contribute at modellers ánd national representatives right momentum for successful inventories More countries go modelling  Map coverage will extend Awareness of (use within) AQD context Needs from country perspective: Need for forum for Exchange/share modelling experiences, difficulties, complexities Harmonisation efforts between (groups of) countires Common pro-active platform / board: provide overview on national activities pro-actively coordinate, facilitate and support in needs Initiate/organise national bilaterals on cross border issues 12 april 2013 Compilation of national modelled AQ maps

Need for an pro-active Common platform / board Do not expect from individual countries much initiative Limited overview on modelling & mapping activities ongoing throughout Europe. Lack of intrinsic interest, versus EEA / EC with such interest. Limited objectivity and neutrality, versus EEA / EC able to assure objectivity and neutrality. Limited capacities further than national. 12 april 2013 Compilation of national modelled AQ maps

Concluding: FAIRMODE can fill needs Provide forum for Exchange/share modelling experiences, difficulties, complexities. Harmonisation efforts between (groups of) countires. Common pro-active platform / board: provide overview on ongoing national activities. Do inventories, like this presented here. pro-actively coordinate, facilitate and support in needs (within AQD context). Initiate/organise bilaterals on cross border issues. 12 april 2013 Compilation of national modelled AQ maps
