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?

3
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 outcomebut

4
Phase 2 - 2nd inventory

• Systematic internet search (May 2012)
• on national sub-national modelling activities
• public information
• Extension
• EEA32 Member Countries
• EEAs 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

5
Based on search results further focus for data
request

• PM10, NO2, SO2
• Annual averages
• most countries
• simple indicator
• 2010
• If modelling ongoing -gt reasonable change data
  available
• Recent year -gt 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)

6
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

• 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

• Conversion of (sub)national projections into
  EEAs 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

Different resolution and orientation

• Composite maps visual analysis on
  discrepancies between countries

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

17
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.

18
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.
