Report on the ESO Workshop "Atmospheres, Atmospheres! Do I look like I care about atmospheres?"

The discovery rate of exoplanets has been such that we have now moved from a simple detection regime to one in which planets can be characterised. Alongside precise determinations of planetary radii and bulk compositions, the properties of their atmospheres are now being revealed. This provides a powerful window onto the formation history of planetary systems, the composition of the initial protoplanetary disc in which planets form, and the locations of planet formation. Moreover, this allows us to study various chemical and thermodynamical processes in the upper atmosphere, as well as to probe planetary interiors. ESO recently organised an online workshop on these topics, with some quite unique aspects: it addressed results from transmission and emission spectroscopy from the ground in the study of exo-atmospheres; it looked at synergies with studies of giant planets in the Solar System; it provided two days of hands-on activities to prepare the future generation; and it included invited talks by the most promising young scientists working in this field.
