Next TFMM meeting(s)


The 26 annual TFMM meeting

5-7 May 2025 in Potsdam, Germany

The registration for the 26th TFMM hybrid meeting, scheduled for May 5–7, 2025, in Potsdam, Germany is now open.

The meeting will be hosted by the Research Institute for Sustainability (RIFS), back-to-back with the TF HTAP meeting.

Logistical information - meeting location, hotels etc

On May 5 and 6, we aim to provide a comprehensive overview of ongoing and planned TFMM activities, with a focus on the next workplan (2026–2027). In the morning of May 7, there will be a joint session with TF HTAP on the planned global-regional exercises related to ozone.

Draft agenda

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

  • O3/VOC with a focus on the July 2022 Modelling Exercise
  • VOC observed and modelled variability + IMP 2024 VOC campaign overview
  • PMs chemical composition, including CEC (measurements and modelling)
  • Short- and long-term transboundary contributions
  • General country update
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 April 4th, 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.
