Wake up, babe. A new zarr just dropped.
The last time I wrote you all, the summer sweltered, determinism was still alive (now it is dead, and only 11 AI weather papers had been published in Nature (now the total is up to 188,732).
If I keep it up y'all are never going to take me seriously. But lo, some seriously new stuff!
HRRR go brrr
HRRR forecasts are live and updating! Check out the release trailer (lol) here.
Give it a try! It'll be like that time in high school when you played too much Elder Scrolls Oblivion during a long weekend, and when you finally stepped outside into nature you thought to yourself "woah, these graphics are incredible."
- Catalog
- Notebook: Github | Colab
- Reformatter code
A massive thanks to Alden, Tony, Alex and Sam for getting this one out there!
Icechunk support
We've also launched Earthchunk Icechunk versions of the GFS and HRRR forecasts. It's internal only until we sort out a few final details, but if you'd feel the need for speed and are prerelease-tolerant let us know and we can hook you up.
weathering
In case you missed it we have a podcast now! We so far have covered:
- The limits of predictability
- End-to-end data-driven weather prediction (Aardvark Weather)
- The Hybrid Approach (NeuralGCN)
- Efficient AI ensemble forecasts (ECMWF AIFS-CRPS, DeepMind FGN)
5 papers down, 188,727 to go! No new AI weather papers allowed.
Scorecard
Hey, wouldn't you know it. Having stuff in this here catalog makes it easier to build things. I was tired of stats against reanalysis as "truth" so Alden and I hacked out a very simple scorecard. When I say simple, I mean simple. For now it's just RMSE for 2m temp and precip. Of course, a few weeks after this went live, ISD-lite was killed in favor of GHCN so I gotta flip that over to keep things live-updating! URGH.
Enjoy the weather.
