Compilation of national modelled air quality maps Peter de smet, Frank de Leeuw (RIVM,NL) Jan horálek, Pavel Kurfürst (CHMI, CZ) ETC/ACM Contact: Report:

Compilation of national modelled AQ maps 2 25 Oct 2013 Original idea 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?

Compilation of national modelled AQ maps 3 25 Oct 2013 Phase 1 – 1 st inventory –Check AQ Questionnaire on model use (EU27, EFTA) AQQ 2010: 5x PM x Benzene (in 2011) –A generic 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 2 nd inventory, despite little expectations on outcome

Compilation of national modelled AQ maps 4 25 Oct 2013 Phase nd inventory –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)

Compilation of national modelled AQ maps 5 25 Oct 2013 Based on search results further focus for data request: Narrow down to: –Annual averages PM 10, NO 2, SO 2 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)

Compilation of national modelled AQ maps 6 25 Oct 2013 By dedicated & personalised –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 ) (Annex 3: persons contacted)

Compilation of national modelled AQ maps 7 25 Oct 2013 Responses: We had little expectations, 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 )

Compilation of national modelled AQ maps 8 25 Oct 2013 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

Compilation of national modelled AQ maps 9 25 Oct 2013 Different resolution and orientation

Compilation of national modelled AQ maps Oct 2013 Composite maps visual ‘analysis’ on discrepancies between countries

Compilation of national modelled AQ maps Oct 2013 Ann. Avg. SO2

Compilation of national modelled AQ maps Oct 2013 Details ann.avg.SO2 (small jumps at borders  carefull interpretation)

Compilation of national modelled AQ maps Oct 2013 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

Compilation of national modelled AQ maps Oct 2013 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. –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.

Compilation of national modelled AQ maps Oct 2013 Concluding: FAIRMODE could fulfil these 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 the one presented here. –pro-actively coordinate, facilitate and support in needs (within AQD context). –Initiate/organise bilaterals on cross border issues.
