Compilation of national modelled air quality maps

1. 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: http://acm.eionet.europa.eu/reports/ETCACM_TP_2013_3_compAQmodelmaps

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

3. Check AQ Questionnaire on model use (EU27, EFTA) AQQ 2010: 5x PM10 - 12x Benzene (in 2011) A generic email to all AQQ contact persons  11 response (Table 1: model data/pollutant/country) Too little to prepare a European composite map We knew there was more!  Launch of 2nd inventory, despite little expectations on outcome Phase 1 – 1st inventory Compilation of national modelled AQ maps

4. Systematic internet search (May 2012) on national & sub-national modelling activities on any public information Extension EEA32 Member Countries EEA’s 7 Cooperating Countries (Annex 1: search results/country) Phase 2 - 2nd inventory Compilation of national modelled AQ maps

5. Narrow down to: Annual averages PM10, NO2, SO2 Most countries model these pollutants AQD-wise Simple indicator Our limited time and resources 2010 If modelling ongoing  reasonable chance data available Recent year  actuality of info & model (version) used Reports + data ‘from-the-shelf’ / ‘fresh-in-the-mind’  little effort to contribute Larger chance on comparability with other map products (Matches year of phase 1 inventory) Based on search results further focus for data request: Compilation of national modelled AQ maps

6. Referring to exact and relevant info found on internet Request for data + some model info + ref. to Model Documentation System (MDS) Indicate we would do: no model benchmarking ! no model performance judgement ! only visual interpretation of composite maps Sent 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: example of email) (Annex 3: persons contacted) By dedicated & personalised email: Compilation of national modelled AQ maps

7. We had littleexpectations, but: 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; IT natl. maps) Responses: Compilation of national modelled AQ maps

8. 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 Composite maps processing: Compilation of national modelled AQ maps

15. Details ann.avg.SO2 (small jumps at borders carefull interpretation) Compilation of national modelled AQ maps

16. 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 Findings from inventory Compilation of national modelled AQ maps

17. Do not expect from individual countries much initiative Limited overview on modelling & mapping activities ongoing throughout Europe. Limited intrinsic interest, vs. EEA / EC have that interest. Limited objectivity and neutrality, vs. EEA / EC able to assure objectivity and neutrality. Limited capacity beyond national activities. Need for an pro-active Common platform / board Compilation of national modelled AQ maps

18. 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 the one presented here. pro-actively coordinate, facilitate and support in needs (within AQD context). Initiate/organise bilaterals on cross border issues. Concluding: FAIRMODE could fulfil these needs Compilation of national modelled AQ maps
