Transnational access to European Research Infrastructures

Research Infrastructures are facilities, resources and services used by the science community to conduct research and foster innovation.

OGTAC-CC call for ACTRIS related training activities on organic tracers and aerosol constituents within the framework of the ECAC-CAIS CF

The OrGanic Tracers and Aerosol Constituents - Calibration Center (OGTAC-CC), hosted and operated by TROPOS ACD as one TC unit of the ECAC-CAIS consortium, is announcing the following activity for all operators of ACTRIS NFs (observational and exploratory platforms), and former EUROCHAMP2020 members as well as to all other interested parties as users:

Theory and practice - determination of organic tracers and aerosol constituents from sampling to the final result demonstrated for the future ACTRIS platforms Melpitz (observational) and ACD-C (exploratory)

OGTAC-CC offers a hands-on training course at TROPOS ACD, Leipzig with the following elements:

  • Dedicated training on sample collection at the Aerosol Chamber ACD-C and recording online data needed for offline data interpretation
  • Dedicated training at state-of-the-art analytical instrumentation
  • Lectures in atmospheric particle related chemical analysis
  • Filter extraction, analysis and quantification of target compounds (mainly biogenics)

The course will be held for 5 days at TROPOS ACD in Leipzig and two different periods are available for choice. The number of participants is limited to 10.
Option 1: Monday, 20th to Friday, 24th of March 2023
Option 2: Monday, 27th to Friday, 31st of March 2023

The operators of future NFs planning to measure particulate organics from filters should consider the participation at the training course as a part of their QA/QC measures.

The training course is funded by the ACTRIS TC operational costs. However, participants have to cover their travel + accommodation costs.
Subscription to the training can be done via mail to:
Registration should take place before January 31st 2023.
We are looking forward seeing you in Leipzig and please don't hesitate to contact Dr. Falk Mothes ( for any questions regarding the training course.



The ACTRIS IMP project offers limited opportunities for free-of-charge transnational access to specific services at 11 ACTRIS facilities comprising Topical Centres (TCs), the Data Centre (DC), National Facilities (NFs), or combined ACTRIS Facilities (NF-TC), located in 10 different countries.

The objective of a TNA pilot is to implement and test the service provision to assess and improve the reliability of the overall service provision within ACTRIS, increase the user trust and expand the user base. Thus, specific consideration will be dedicated to projects focusing on the following aspects:

–  technological development, training, forefront scientific exploration, or potential for evolving user needs,

–  projects with high potential for involving users from the private sector for prototype testing, joint developments, and industrial applications, and

–  projects attracting new users from new/relevant regions, other scientific domains for multi-disciplinary applications, or tailored user services.

Timeline of the call :

  • Publication date: 22 July 2022 
  • Access period: October 2022 – August 2023


The Atmospheric Chemistry Department – Chamber (ACD-C) in combination with the OrGanic Tracers and Aerosol Constituents - Calibration Centre (OGTAC-CC) will provide trans-national access (physical access) to both infrastructures in the framework of the ACTRiS IMP TNA pilot.

ATMO-ACCESS is the organized response of distributed atmospheric research facilities for developing a pilot for a new model of Integrating Activities. The project will deliver a series of recommendations for establishing a comprehensive and sustainable framework for access to distributed atmospheric Research Infrastructures (RI), ensuring integrated access to and optimised use of the services they provide.

ATMO-ACCESS will open physical and remote access to 43 operational European atmospheric research facilities, including ground-based observation stations, simulation chambers, but also mobile facilities and central laboratories that are fundamental elements in distributed RIs.

The call timeline is as follows:

  • Call dates: 10 Oct 2022 -5 Jan 2023
  • Info day for users and providers: 7 Dec 2022 (virtual)
  • Feasibility until 20 Jan 2023
  • Review until 17 Feb 2023
  • Final selection meeting 20-24 Feb 2023
  • Final list on 28 Feb 2023
  • Indicative access period: March 2023 / March 2024
