Next TFMM meeting(s)


The 27 annual TFMM meeting, Bled, Slovenia, 28-29 April 2026

We are pleased to announce the opening of registration for the 27th TFMM hybrid meeting, scheduled for April 28–29, 2026, at Hotel Park at Bled, Slovenia. The meeting will be hosted by the Meteorological Synthesizing Centre – East (MSC-E) - Department of Environmental Sciences at the Jožef Stefan Institute (JSI) in Ljubljana, Slovenia.

On April 28 and 29, we aim to provide a comprehensive overview of ongoing and planned TFMM activities, with a focus on the TFMM workplan (2026–2027).

Apart from the update on the Convention and the discussion on synergies between the TFMM workplan and challenges related to the 2024/2881 directive, we are particularly interested in contributions to the following topics:

  • VOCs contribution to O3 pollution over Europe
  • Source Apportionment modelling applications
  • Aerosol chemical speciation, secondary aerosols, condensables and CEC
  • Natural contributions and Long-Range Transport
  • Country updates
TFMM is always open for broad cooperation with the scientific community — please feel free to share the link with your colleagues.

Please complete the registration form at your earliest convenience and no later than March 27th COB, and indicate if you intend to provide a presentation:

Intensive Measurement Periods (IMPs) on VOCs in 2022 and 2024

In July 2022, one week of intensive measurements of various VOCs (NMHCs, O-VOC, terpenes) and biogenic aerosol tracers was conducted during a heatwave (July 12-19). The goal was to assess the role of different ozone and aerosol precursors during heatwaves. Preliminary results were presented at the 24th annual TFMM meeting and in Chapter 6 the EMEP status report 2023.

In September 2024, around 40 sites with high-resolution VOC, O₃, and NOₓ monitors conducted continuous measurements for at least three weeks. The aim was to better understand VOC emissions, including their temporal variations and speciation. High-resolution measurements were prioritized near emission sources, with additional manual sampling at some sites for detailed source fingerprinting. This IMP is a collaboration with ACTRIS and RI-URBANS, and initial findings will be presented at the 26th TFMM in 2025.
