just published #python package for #healpix regrid of data from and to #parquet file using #duckdb and other neat tricks for speed up.

Still very immature, check if this can be useful.

[PATCH 00/38] Astro update 2024/12

Justus made a great intro on using #DGGS through #xarray #xdggs at the #Pangeo showcase talk. Xdggs is now in a stage where you can use it fairly robustly with #HEALPIX and #H3. Other integrations like for #DGGRID are developed as separate plugins.

[PATCH 00/26] Astronomy update 2024/09

While working on the Guix Astro update for this month I've learned that the source may be closer than expected (7 libraries share the same VCS, depending on each other).

Other findings - the famous Cosmic microwave background image was produced by the software I'm about to pack - HEALPix.

Ever wondered how #nextGEMS wants to achieve simulating processes spanning a 30-year period on a kilometer scale?

Check out our newest blogbost to find out and to learn about why hierarchies, chunkig and the #HEALpix grid play an important role in efficient regional climate modelling.

Thanks Lukas Kluft and Tobias Kölling for sharing your insights with us!

Of hierarchies, chunking, and HEALPix

The key goal of the nextGEMS project is to produce the first-ever km-scale simulations that span a 30-year period, i.e., “one climate”. This produces an immense amount of output data even for single variables, in fact, the number of grid points in a …
