Background
 Both EEA and EMEP have strategies that includes
further use and development of NRT AQ data
 Important to avoid duplication of efforts –both for
the individual Member States/Parties to the
Convention, and for EEA/EMEP CCC –and to benefit
from each others work
 A feasibly study has been carried out in 2008-2009:
To provide recommendations on a strategy for NRT
AQ data sharing and exchange, based on the needs
and requirements from EMEP and EEA.
Why access to NRT data ?
1. Increased public awareness
2. Improved QC/QA of AQ data
3. Faster response in case of instrument failure etc,
meaning improved quality
4. Facilitated data flows and reporting
5. Improved understanding of processes and impacts
from air pollution
6. Improved forecast of emergency AQ situations
Specific motivation for EMEP and the
research community for NRT data
1. Better understanding the development of special
pollution episodes (forest fires, dust storm, ....)
2. Better planning of research campaigns
3. Better calibration and validation of satellite data (not
necessarily NRT, but rapid data access )
4. Better understanding of the interactions between air
pollution and climate (by assimilation into weather
prediction models)
The different needs for NRT air quality data
 EEA needs NRT data to inform the public and to support
the EU policy cycle for air quality legislation
 I.e: O3, NOx, SO2, PM10, PM2.5
 Indicator and exceedance reports, i.e ozone summer reports
 EMEP needs NRT to improve understanding of the
processes and impacts of air pollution and their link to
climate
 GMES to be discussed by Leonor Tarrason
EMEP Monitoring strategy 2010-2019
15. ……EMEP will, where relevant and appropriate, introduce monitoring
of parameters at a timeliness allowing more rapid access to data on the
air pollution situation across the EMEP domain.
EMEP will in collaboration with the European Environment Agency (EEA)
contribute to the provision of near-real time data for Global Monitoring for
the Environment and Security (GMES) in agreement with the Parties.
Such efforts will be based on voluntary contributions from Parties and
will follow the guidance of the EMEP Steering Body.

 Note that reporting of NRT is voluntary.
 A strong link to the science community
NRT in EUSAAR (EU FP6)
• Establish NRT data flow at selected supersites
• Develop web based, restricted access data
visualization (non official preliminary data)
• Develop tools for QA/QC and official data submission
• Priority parameters

•
Scattering Coefficient (nephelometer)
Particle Size Distribution(DMPS /SMPS)
Absorption Coefficient ( MAAP/PSAP/Aethalometer)
PM10, PM2.5, PM1

Other relevant project with NRT or
rapid data delivery

Overlapping NRT parameters (EEA /
EMEP)
Monitoring programme:
Level 1
•Main ions in precipitation and in air
(incl SO2, NO2)
•heavy metals in precipitations
•ozone
•PM10 and PM2.5 mass
•Low cost nitrogen gas/particle
•meteorology
at ca 125 sites
Level 2, supersite (joint EMEP/GAW)
•EC/OC and mineral dust in PM
•Optical and physical properties of
aerosol
• VOC
• CO
• CH4
• halocarbons
• POPs
• Heavy metals in air and aerosols
20-30 sites
Overlapping NRT parameters (EEA /
EMEP)
• Overlap for EMEP level 1 measurements:
PM10, PM2.5 , O3, NO2, SO2. But only O3 with monitor
as reference method. Though increased nr of sites
with monitors for NOx and PM
• Duplication of work can be avoided by re-using
capacities and data. Any overlap in NRT data request
must be avoided by EMEP and EEA and managed
through IT, data sharing or organizational solutions.
Conclusions and recommendations
 EMEP-CCC and EEA shall act as thematic nodes for NRT data.
EMEP/CCC on “supersite” data and EEA on “Airbase” data
 Standards for data sharing and exchange are needed. EEA and
EMEP/CCC should undertake further work on standards to
identify what can be (re-)used , in particular from SEIS,
INSPIRE, and GMES . Have in mind also other bodies with
interest in NRT AQ data
 refine the description of requirements on timeliness and to use
standards for metadata description
 Better qualify the status and the quality of NRT AQ data, i.e
replace preliminary data after a period with official data sets
 NRT data exchange standards could become the basis for
other data provision and streamlining
Thank you for the attention!
