abstract
After a successful kick-off meeting in 2021. two workshops in 2022 and 2023 on the future Global Cosmic-Ray Observatory (GCOS) focused mainly on a straw man design of the detector and science possibilities for astro- and particle physics. About 100 participants gathered for in-person and hybrid panel discussions. In this report, we summarize these discussions, present a preliminary straw-man design for GCOS and collect short write-ups of the flash talks given during the focus sessions.

Detection of Spaceborne Lasers with the Pierre Auger Observatory
Fluorescence telescopes at the Pierre Auger Observatory detect and reconstruct laser tracks from the Aeolus and EarthCARE space lidars, providing satellite ground-truthing and a possible cross-calibration of cosmic-ray energy scales.
