Announcing the Earthmover Data Marketplace: cloud native access to high-velocity gridded weather, climate, and E/O datasets. Get seamless access to data from trusted providers, including forecasts from @ecmwf.int, @noaa.gov, and exciting new AI-based forecasts! Visit: app.earthmover.io/marketplace

🧊 Icechunk 2 is now available in alpha: Move/rename nodes without rewriting, shift chunks without consuming I/O, write metadata at the repo level, and so many performance improvements. Check out @rabernat.bsky.social and @seabass.bsky.social 's post to get the full list!

Today @rabernat.bsky.social is at the @nationalacademies.org in DC participating on a panel about governance models for Earth data with @ecmwf.int, @esipfed.bsky.social, @wmo-global.bsky.social and more: we only wish we all could attend "Future Directions for Earth Observations and Stewardship"

Xarray, Zarr, and Icechunk together offer the best all-around developer experience for working with tensor data in the cloud- AND best-in-class performance for I/O bound workloads. Check the performance benchmarks @rabernat.bsky.social posted on our blog: earthmover.io/blog/i-o-max...
