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 CAIS-ECAC

The OrGanic Tracers and Aerosol Constituents - Calibration Center (OGTAC-CC), hosted and operated by TROPOS ACD as one TC unit of the CAIS-ECAC 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 - LC-MS analysis of organic tracer compounds and determination of organic and elemental carbon (OC/EC) from particulate matter collected on filters

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

  • Introduction and presentation of sample collectors, preparation devices and analytical instrumentation
  • Dedicated hands-on training at state-of-the-art analytical instrumentation (LC-MS and OC/EC) including filter extraction, analysis and quantification of organic tracer compounds
  • Demonstration of sample collection during an experimental run at the atmospheric simulation chamber ACD-C, on-site offline analysis and data interpretation
  • Lectures in atmospheric particle related chemical analysis

The course will be held for 5 days from Monday, 6th to Friday, 10th of November 2023 at TROPOS ACD in Leipzig. The number of participants is limited to 8. In case more applications are received a second course from Monday, 13th to Friday, 17th of November 2023 could be optional.

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 September 20th 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.

With best regards,

Falk Mothes and Hartmut Herrmann



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.

- TNA access for private sector (open until end of the year) :

- TNA access for Urgent request (always open):


The turbulent Leipzig Aerosol Cloud Interaction Simulator (LACI-T) will provide trans-national access (physical access) in the framework of the ATMO-ACCESS.
