I’ve got some exciting news to share. @rabernat and I have started @EarthmoverHQ, a new company with a mission to empower people to use scientific data to solve our planet’s most urgent challenges. twitter.com/EarthmoverHQ/s…

We watched data teams waste years building the same ingestion pipelines for weather data. So we fixed it. Zero ingestion. High velocity. Cloud-native. Proud to launch with incredible partners like @brightbandtech, #zeusai, and dynamical.org. Give it a spin! 👇

@mouthofmorrison @lowercarbon Thanks for the kind words Joe!

Congrats to their maniacal, unreasonably talented team (especially Ryan and Joe) and @lowercarbon for the pick. earthmover.io/blog/earthmove…

My entire career I’ve been riding a wave of petabyte-scale sensor data as connected devices proliferate on Earth and in space. But it turns out most of that data is totally inaccessible due to lack of tooling to query and understand it. Earthmover is our best hope to fix that.

CEO @rabernat, CTO @_jhamman & the Earthmover team are out and about at #ClimateWeekNYC - and registration is still open for Wednesday's workshop, 'Open Data in Applied Risk Analysis' and Thursday's panel, 'Bridging Earth Observation & Risk Analytics at Scale.' Join them!

#ClimateWeek NYC is coming soon: register for the events @rabernat & Earthmover will attend here: m.earthmover.io/events - including a Future of AI Weather Forecasting panel with @brightbandtech @nvidia @sorcerer_earth & @Google

Running AI weather models in the cloud? Here are 3 optimizations that radically cut cost and keep those GPUs busy earthmover.io/blog/the-3-key…

No more bespoke APIs. No glue code. Just fast, interoperable access via tools you already use — QGIS, ArcGIS, web maps, Python, R, MATLAB, and more. Flux is a cheat code for building data products.

🚀 Big launch today: introducing Flux — a game-changing way to serve geospatial data via standard APIs in seconds. Built for scale, speed, and simplicity.

1/ 🚀 Solving #NASA ’s cloud data dilemma: Icechunk unlocks 100x faster access to archival data formats We're thrilled to publish results from our pilot project with @NASA + @developmentseed to enable high-performance cloud-native access for NASA’s 100s of PBs of EO data.

We're moving over to BlueSky and LinkedIn for all our future announcements. Follow us at bsky.app/profile/pangeo… to find out more about tomorrow's showcase 😉 (p.s., it's on Xpublish at Scale at 4 PM EST 🚀) Connect with us on LinkedIn at linkedin.com/company/pangeo…

🌍 As we digitize the analog world, new data formats unlock exponential value. @EarthmoverHQ's open-source Zarr and Icechunk are redefining how we organize and compute massive geospatial datasets, scaling solutions for problems once thought inaccessible. 🔊 Links 👇

🌎 Why do we need a cloud-native data lake for geospatial data? In the latest episode of The Infra Pod, @tnachen & @ianlivingstone chat with the cofounders of @EarthmoverHQ, @rabernat & @_jhamman, about the future of data in climate and earth sciences. 🎧 Link in 🧵

If you’ll be at #AMS25 and love weather data, join us for a @pangeo_data Community Happy Hour! We’ll have drinks, appetizers, and great conversation with friends old and new about technology, weather & climate data, and open-source software! Register: lu.ma/ddtba5f5

We’re thrilled to announce the release of @zarr_dev-Python 3! This major release brings full support for Zarr v3 specification, including the new chunk-sharding extension, major performance enhancements, and a thoroughly modernized codebase. Read more: earthmover.io/blog/zarr3-rel…

The 3.0.0 release clears the way for a bunch of exciting extensions built on top of the v3 spec. #icechunk, variable chunking, new dtypes, and more are all now possible. Time to get busy.

One of the best parts of this release is that it included contributions from over 30 people. After a period of slow development, the v3 refactor really managed to build momentum in the project. Special shout out to @normanrz and Davis Bennett for doing a big chunk of the work.

We released Zarr-Python 3 today, complete with support for the v3 spec, new extensions (chunk-sharding) and significant performance gains. earthmover.io/blog/zarr3-rel…
