ACTRIS

Aerosols, Clouds, and Trace gases Research Infrastructure Network

Type of funding scheme: Combination of Collaborative Projects and Coordination and Support Actions for Integrating Activities

Work programme topics addressed: FP7-INFRASTRUCTURES-2010-1

Support to existing research infrastructures/ Integrating Activities

INFRA-2010-1-1.1.16: Research Infrastructures for Atmospheric Research

1 April 2011 – 31 March 2015

ACTRIS aims at integrating European ground-based stations equipped with advanced atmospheric probing instrumentation for aerosols, clouds and short-lived gas-phase species.

ACTRIS will have the essential role to support building of new knowledge as well as policy issues on climate change, air quality and long-range transport of pollutants.


The actris research infrastructure in support to emep

  • The main objectives of ACTRIS are:

  • To provide long-term observational data relevant to climate and air quality research on the regional scale produced with standardized or comparable procedures throughout the network

  • To develop new integration tools to fully exploit the use of multiple atmospheric techniques at ground-based stations, in particular for the calibration/validation/integration of satellite sensors and for the improvement of the parameterizations used in global and regional-scale climate and air quality models

  • To provide trans-national access to large infrastructures and access to high-quality information and services for the user communities (research, Environmental protection agencies, etc.)

  • To enhance training of new scientists and new users in the field of atmospheric observation

  • To promote development of new technologies for atmospheric observation of aerosols, clouds and trace gases through close partnership with EU SMEs

ACTRIS as a Long-term Sustainable Research Network

ACTRIS is not a research project but a research infrastructure (long-term vision)

Existing – step further – long term

  • Maintain the state of the art of the observations

  • Technological and methodological developments

  • Fill existing gaps

  • Integration (observation strategy, synergies, methodology , products and database)

  • Sustainability for long term observations

ACTRIS NA4: volatile organic compounds and nitrogen oxides

Objectives

• To integrate and harmonise trace gas measurements in Europe.

• To implement SOPs and common European calibration scales for

VOCs and NOxy in support of EMEP and GAW.

• To create a protocol for merging the information of ground-based in-situ and remote sensing capacities.

• To foster the dissemination of the methods and quality assured data to scientific groups dealing with the analysis and modeling of air pollutants in Europe (support of EC air quality directives and the CLRTAP abatement strategies).

ACTRIS TNA12: Access to AERONET-EUROPE ground-based automatic sun/sky-photometer (level 2) Calibration Service

  • -Rationale: To enable AERONET network expansion, alternative calibration centers have been developed in Europe under the leadership of CNRS-LOA in France (Lille), then in Spain by GOA (Valladolid) and by AEMET (Izaña).

  • -Objective: The main goal of the AERONET-EUROPE Service Activity is to operate this multi-site European infrastructure to provide calibration to European AERONET members.

  • - Service:

  • post-field calibration-maintenance then pre-field calibration sequence;

  • final functional test in LOA or GOA;

  • calibration update in AERONET database;

  • request Quality Assurance analysis to GSFC/NASA.

  • Continuity of observation during calibration phase can be requested to the AERONET-EUROPE service.

Conclusions

  • - ACTRIS covers many variables for which there is no (or several) reference methods

  • ACTRIS has the mandate to support long term monitoring networks (EMEP, GAW)

  • ACTRIS services can be accessed by:

  • Using trans-national access (TNA)

  • Becoming an associate.
