 notes: The building is locked after 5pm. Someone will be there 5-10 minutes until 6pm to let us in at the entrance near the bike shelter at the northwest corner of the building. If you see nobody around and can't access, ping the CUGOS Slack to be let in. We will adjourn to a nearby pub for a happy hour after the meeting!

+**[Keenan Ganz](https://s-kganz.github.io)** will talk about converting an archive of radar imagery from a legacy storage format (NetCDF) to a cloud-optimized format (Zarr). This will be a 201-level follow-up to last month's talk about cloud-native geospatial, with more details on chunking, I/O rates, and of course, dead trees.
