First Bern Meeting

During the first ATTACK meeting in Bern the team discussed topics related to a) the atmospheric chemistry, b) the haze/cloud formation and interaction with the background atmosphere, and c) past, current, and future observations for the gas abundances and haze/cloud properties. The team has identified tasks and activities to be followed within each of the above topics that would help advance the understanding of Titan’s atmosphere in terms of chemical composition and dynamics. These include activities pertaining to improving the photochemical networks in order to indemnify expected species in the atmosphere, obtaining new detections or upper limits and setting new constraints on unidentified gas species from observations by  exploring the potential of investigating experimentally and/or theoretically heterogeneous processes in Titan’s atmosphere. Better defining the degree of complexity in Titan’s atmosphere  will help define the observations expected by future missions such as Dragonfly and from the ground. The team will reconvene in the spring of 2026, while regular bimonthly online meetings are scheduled for discussing the projects progress.
