Compilation of national modelled AQ maps 212 april 2013
Original ideaOriginal 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?

Phase 1 – 1Phase 1 – 1stst inventory 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:

Phase 2 - 2Phase 2 - 2ndnd inventory 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

Based on search results further focus for Based on search results further focus for data request: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)

By dedicated & personalised email: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)

Responses: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)

Composite maps processing: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

Findings from inventoryFindings 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
![Page 17: Compilation of national modelled air quality maps](https://reader033.fdocuments.net/reader033/viewer/2022051623/5681584e550346895dc5a70c/html5/thumbnails/17.jpg)

Need for an pro-active Need for an pro-active Common platform / boardCommon 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.

Concluding: Concluding: FAIRMODE can fill needs 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.
