Zarr in the News

[joshmoore]

Similar to the ongoing conversation in "Regular zarr/n5 community conference calls" (https://github.com/zarr-developers/zarr/issues/315), this is an ongoing place to post blogs posts and another announcements about Zarr that everyone is aware of.

Mention of Zarr:

Outside of Satellite imagery, Ifremer has used Pangeo on our cluster to analyze the outputs of a big ocean simulation (MitGCM LLC4320). One typical thing done on this simulation is the computation of time-frequency kinetic energy spectra, which basically build a big datacube over the globe and reorganize the data so as to have the full temporal axis on a given location in memory in order to perform the scientific computation on it. Xarray helps to do this in very few lines of code, and by using Zarr file format they were able to speed-up the data loading by a factor of ten compared to NetCDF.
