DAEDALUS EC 5th framework: aerosol users survey Olivier Boucher Laboratoire d ’Optique Atmosphérique USTL / CNRS, Villeneuve d ’Ascq, France Gerrit de Leeuw TNO, The Hague, Netherlands and the DAEDALUS team
DAEDALUS: an FP5 GMES project Delivery of AErosol proDucts for Assimilation and environmentaLUSe • specially written for the recent • GMES call for proposal of the EESD • 3 year project: Jan 2003 - Dec 2005 • 7 partners: F, B, NL, N, P + JRC • run in parallel with another “aerosol” • EC project (CREATE)
Reasons for getting interested in atmospheric aerosols: • visibility ==> tourism, aviation • air quality issues ==> human health, ecosystems • deposition and acid rain issues ==> ecosystems • climate effect (clear-sky, cloudy-sky) • - anthropogenic aerosols are responsible for a radiative forcing • - anthropogenic aerosols may modify the hydrological cycle • - natural aerosols may response to climate change • satellite atmospheric corrections • ==> retrieval of the properties of ocean, land, and atmosphere • role of aerosol deposition on ocean biology • improvement in meteorological (re)analysis • improvements in weather forecasts ? • depletion of the stratospheric ozone layer
As aerosol concentrations increase and visibility decreases, there is - a whitening of the landscape, - loss of texture, - loss of contrast.
WP1: Users needs * 2-page questionnaire on tropospheric and stratospheric aerosol products * Questionnaire was sent out by e-mail to over 200 people across Europe * 33 answers received so far (most are users, some producers, some inconsistencies) * Several talks and posters presented at this workshop CERMES, ADEME, EPA Ireland, …
Role of organization 4 University + 15 Research Centres
Aerosol properties of interest 97% of users interested in aerosols (3% in gas species) 91% of users interested in tropospheric aerosols 38% of users interested in stratospheric aerosols
Satellite Data 97% of users would consider satellite data if available and in a suitable format Spatial resolution Time resolution (average) Timeliness
Model Aerosol Forecast 67% of users would consider model forecast if available and in a suitable format Spatial resolution Time resolution (average) Timeliness
Conclusions • 200 potential users contacted; 33 answers • Semi-quantitative analysis of answers BUT • each user is unique • we should not try to please an “average” user • some users not covered (aviation, army, ...) • Interest for both tropospheric and stratospheric aerosols • Very positive feeling for satellite data • Positive feeling for model forecast (near real time needed) DAEDALUS / users dinner scheduled at 8.30pm Mexican restaurant 7 Koningin Wilhelmina Boulevard, Noordwijk Reservation for 10 +/-2 people made

Results: information on aerosol 2. Model application
Lessons learned / Recommendations • CREATE • Emission databases are not accurate enough to predict evolution of aerosol fields over Europe • Validation of satellite derived aerosol products is needed from in-situ ground truth and vertical profile (sunphotometer / lidar) data • Measurement programmes should have long term continuity and not subject to vagaries of short term funding • Observational capacity needs to be increased • DAEDALUS • Difficulty in accessing and distributing processed data from ESA • Availability of model results and forecasts should be improved. • No infrastructure for a fully-European network of sunphotometers (e.g., integration of PHOTONS / GAW needed) • Ingredients start to be available for an operational aerosol monitoring system although some work still needed for satellite aerosol retrieval and assimilation techniques.

Atmospheric aerosols are particles of natural or anthropogenic origin in suspension in the air. Typical sizes of 10 nm to 100 m, with different roles of the very fine mode (below 100 nm), accumulation mode (0.1 to 1 m), and the coarse mode (1 to 10 m). Chemical composition varies: sulfate, nitrate, organics, black carbon, sea salt, dust, (may also carry some carcirogenic compounds) Particulate matter: PM1, PM2.5, or PM10. Typical lifetime of 5 to 10 days in the lower troposphere.
