Workshop on Ground-level Ozone Forecasting

21 – 23 February 2000, Langen (Germany)




Recommendations:

Ozone measurement data should be made publicly available on the Internet, preferably using a standard format. The data should appear in near real time, i.e. with a maximum delay of 6 hours. The measurement stations should at least include rural stations at neighbour distances less than 200 km.

In addition to ozone, but with a smaller priority, real-time measurement data should be available for other air pollutants of relevance for the photochemical mechanism, viz. CO, NOx and a few VOC compounds. Now to be added: Aerosols, PM

Measurement data




Recommendations:

Regularly updated quality-assured air pollution emission inventories should be made available to the forecast models. These inventories should involve both anthropogenic and biogenic emissions, and should cover Europe including East Europe.

Forecasting models should be evaluated using harmonised procedures.

Methods suitable for assimilation of air pollution measurement data in forecast models should be developed.

Modelling




Recommendations:

A list of web sites, at which ground-level ozone forecasts for European areas are presented in real time, will be made available from EUMETNET’s home page (http://eumetnet.eu.org), and possibly also from EEA’s home page (http://www.eea.eu.int).

EFNet




The first step: AnalysisThe quality of the air has not significantly improved during the past years. During the hot summer 2003 the threshold values for ozone were exceeded very often and may have contributed to a number of deaths




Additional to ozone particulate matter (PM) has become an even more sincere problem




The situation has not changed very much since 2000.

There are many different models and measurements.

But:

• The distribution of the results and the information of the population is insufficient.

• Only few measurement data are internationally exchanged.

• Because of the lack of an operational data exchange the verification of forecasts and the development of initial fields is inhibited.

• Because of the lack of an international exchange of models results and measurement data the improvement of models is impeded.

Recommendations of the Langen Workshop on Data Exchange

Data availability (real time, max delay of 6 hours)

1. O3

2. Second priority CO, NOx, VOC (a few)vertical profiles+ meteorological parameter (wind, T, radiation, H2O at same location)

non urban / typical distance 200 kmknown quality – quality controlledstandard formats and retrieval protocols (perhaps not central storage)

Now to be added: Aerosols, PM




Basic idea of EFNet:

to collect environmental forecasts and measurements

and to make them available to

the public

Organisation Advantages Disadvantages

WMO RA VI Official intergovernmentalnetwork covering the whole ofEurope.

Very formal structure with long decisionmaking processes.

EMEP Already active in air qualitymodelling, combining scienceand policy support.

Focus on international conventions andclimatological evaluations.

This solution would lead to a concentrationof air quality modelling in one institution.

EUMETNET Organisation of the Workshopon Ground-level OzoneForecasting (21-23 Feb. 2000,Langen, D) and cooperationwith EEA during several years.WG-ENV has developed thisproject proposal.

A large number of NMSsinvolved.

WG-ENV has had a low profile and not thefull coverage of the EUMETNET MemberStates. However, this may be correctedthrough the proposed dedicated andinnovative initiative.

ESA-servicein theframework ofGMES

This approach could becoupled with the networkapproach.

More concerned on using satellite-bornedata that are often unfeasible for low-tropospheric applications. Thus does notcover all aspects necessary for a ground-level forecasting service.

Products of the EFNet could be: Presentation of analyses and observations of various

concentration products (Ozone, NOx, PM, etc.). Near-real time operational forecasts of ground-level

ozone, NOx and particles (PM10, PM2.5). Grouped presentation of forecasts from various models

(multi-model forecasts and statistics), thus enablingensemble prediction capabilities (PEPS)

Statistics from some of the above products for the sakeof: operational quality assurance (for the public, Web

site), detailed scientific assessment of the models quality.




Products of the EFNet could be:

Forecast fields and point values using predefined abatement scenarios in order to show the ”would-be” influence of these standard emission reduction scenarios;

Results from statistically corrected forecasts (urban and rural areas) and statistical models;

A web-site for the public, for users and for the research community.
