EMEP measurements An update from CCC on various ongoing and planned activities
Wenche Aas, Kjetil Tørseth, Cathrine Lund Myhre

2. Content EMEP POP passive measurement campaign
Revision of Data quality objectives (DQO)
Observation data reporting and provision to users

3. EMEP POP passive measurement campaign (2006 and 2016)
EMEP Passive air samplers summer 2006 (Halse et al., 2011)
Repeat 2006 campaign this summer (2016)
Deployed for 3 months
PCBs, HCHs, DDTs, HCB, PAHs and chlordanes
93 sites in 39 countries
(7 more than in 2006)

4. Data quality objectives, level 1
Significant development for advanced measurements (EUSAAR/ACTRIS)
inorganic
Heavy metals
10% accuracy or better for oxidized sulfur and oxidized nitrogen in single analysis in the laboratory
15% accuracy or better for other components in the laboratory
0.1 units for pH
15-25% uncertainty for the combined sampling and chemical analysis (components to be specified later)
90% data completeness of the daily values
Data quality is not evolving in line with what could be expected
The DQOs do not reflect the present need for accuracy

5. Lab intercomparisons annually
Inorganics per cent dev. from expected value
heavy metals
> DQO
> 2x DQO

6. Now possible to link data in the database with lab performance, but not broadly discussed how to best do this
inorganic data
Heavy metal data
EC OC data

7. Technical Workshop autumn 2016
CCC sent an to all Parties to review the needs on technical workshop on the topics:
Data quality (lab and field methods), and defining new data quality objectives
Data handling and data submission
Defining new templates for POPs and HM
interests in attendance received from:
Armenia, Belgium, Czech rep, France, Hungary, Georgia, Iceland, Slovenia.
more responses from participants to TFMM welcome

8. Some open questions and remarks
Is there a need to update the DQO and if yes, how?
A workshop is autumn on data handling and submission incl how to best include metadata on data quality
Input on specific metadata for POPs and HMs is highly appreciated
Please contact the CCC after TFMM with your views and suggestions.

9. The total number of visits to EBAS web interface is 51 350 from more than 90 countries since 2011 (end 2015)

10. Transfer of Reactive gases data from WDCGG (JMA) to NILU -> establishment of the GAW-WDCRG.ORG
Follows the GAW-WDCA arrangement
Joint EMEP + GAW sites: affiliation of data

11. New data reporting templates in progress
Towards a streamlined data reporting portal at EBAS (ebas-submit.nilu.no)
New data reporting templates in progress
More extensive documentation of meta-data (instrument specific, data originator etc)
Updated: aerosols, VOC, O3
Resubmission of historic data?
Launch of the EBAS-submit tool for file format checking upon data submission

12. Online http://ebas-submit-tool.nilu.no

14. Other developments at EBAS
Open Archives Initiatives-Protocol Metadata Harwest (OAI-PMH) server established (WMO WIS Data Collection Production Centre compliant)
Data versioning functionality
Considerations wrt to DOI support
Secondary portals is still a challenge

15. Collaboration with RECETOX in relation to POPs data, Global Monitoring Plan - Data Warehouse

16. Increased Arctic focus; Collaboration with AMAP, IASOA and SAON.

17. Copernicus Atmospheric Monitoring Service (CAMS) and EMEP NRT
No formal data provision (yet?)
«Arctic pilot» (IASOA ozone assessment)

18. NRT data viewer available soon at: http://ebas-nrt-showcase.nilu.no !
