The hybrid CACTI workshop in 2023 took place at GEOMAR in Kiel, Germany, with an option to join online, from Tuesday 13 June to Thursday 15 June 2023. The workshop featured presentations, discussions groups and poster presentations.  

The goal of the CACTI workshop in 2023 was to review the progress since the last TriMIP workshop (TriMIP-3) that brought together the active and collaborative communities of AerChemMIP, RAMIP, RFMIP, and PDRMIP. This workshop focused on advances in our understanding since AR6, identifying gaps and informing future research directions in the community of “Composition Air quality Climate inTeractions Initiative (CACTI): Emissions to Response”.

We’d like to say thank you to all participants, either from online or on site, for sharing the scientific work and contributing to fruitful discussions. We are pleased to share with you a group photo that was captured during the workshop.
