A panel of AI Weather experts from Brightband, Earthmover, Google, NVIDIA, and Sorcerer will discuss the future of AI weather forecasting, and answer questions…

See how modern data workflows let meteorologists deliver market-moving insights to traders with speed and precision.

Icechunk brings Git-like version control to Zarr. Ensure atomic updates, consistent reads, and scalable collaboration for shared datasets.

From structure to scale, radar needs a model that organizes complete collections as time-aware, cloud-native datasets. In our second post, we looked at how new standards and open-source tools are tran...

🌏 50 Years of ERA5 Access in Earthmover: The Arraylake / Icechunk edition is an analysis-ready dataset that retains only the single-level surface fields—18 hourly variables such as 2 m temperature, 10...

At Earthmover, we’re interested in weather radar data for two reasons: We’re obsessed with data like this–which doesn’t fit into either traditional relational databases or into the standard “geospatia...

What Zarr is, and how it enables fast, scalable access to multidimensional array data in the cloud.

We recently got an interesting question in Icechunk’s community Slack channel (thank you Iury Simoes-Sousa for motivating this post): I’m new to Icechunk. How is the storage managed for redundant info...

In this post we’ll show what can happen when more than one process write to the same Icechunk repository concurrently, and how Icechunk uses transactions and conflict resolution to guarantee consisten...

What cloud-optimized data really means, and how Zarr and Icechunk enable fast access to massive scientific datasets in cloud object storage.

We show Icechunk can scale to extremely high concurrency levels, and explain how it achieves this in modern object stores.

Why tabular tools trip over gridded data.

Come have a drink, grab a bite, and nerd out with the Earthmover team on geospatial data. Earthmover will provide food and drink tickets. Our event will be…

We have recently dramatically improved the performance of Xarray’s Zarr backend. This post explores how we’ve improved the “time to first byte” metric, building on Zarr-Python’s new asyncio internals.
