TF HTAP spring meeting will occur at the Research Institute for Sustainability – Helmholtz Centre Potsdam in Germany (previously known as IASS Potsdam) from May 7-9, 2025. This will be a hybrid meeting, with the possibility of online participation for those who can’t make it to Potsdam. We will hold this meeting back-to-back with the Task Force on Measurements and Modelling (TFMM), another task force under the Convention on Long-Range Transboundary Air Pollution, primarily focusing on regional modelling and measurements in the European region. We plan on holding a joint TF HTAP-TFMM session on May 7 to discuss areas of overlap between our two task forces.

This meeting will be immediately preceded by a meeting of the CLRTAP Task Force on Measurements and Modelling (https://emep-ccc.nilu.no/tfmm), and will include a joint session on Wednesday, May 7 for discussion of global-to-regional coupling of model simulations in the OPNS exercise. Registration for the TFMM meeting should be done separately via the TFMM website. Please register for the HTAP meeting here.
The event will be broadcast live via the Zoom application.
