Yay! Just discovered via Github that Unidata received its latest funding tranche and their developers are back to work!

I am really looking forward to a time when scientific data analysis is less of a constant fuckaround and fight with technical bullshit. I'd *really* like

- #netCDF natively supporting complex numbers
- #Python #xarray and #pandas to natively support physical units (#pint is great on its own but the integrations leave a LOT to be desired)
- #Jupyter notebooks to suck less (crashes, glitches, widget plots not saved statically, an effing BUILTIN formatter, etc.)
- proper data pipeline systems
...

Satisfaction comes from wherever you can get it. An issue I filed on Github in 2021 and which users gradually piled onto to say, oh yeah, we need that? It's resolved!

New release of my software coming in the next couple days.

how to tell if #netcdf was compiled with s3 support ? (on linux, just installed from RPM)

even an example netcdf url that should work from a bucket would be helpful

🎉 Generate spreadsheet templates for recording data and metadata for CF-NetCDF files! 🚀

The latest update adds a sheet for variable attributes—metadata describing each variable.

🔗 nordatanet.no/aen/template-gen

Templates bring structure and enable automated CF-NetCDF creation with scripts. In the future, I plan to develop a converter tool ion top of this—upload a template, download a CF-NetCDF!

Excited to share that I'm now a member of the CF Conventions Committee! 🎉

CF (Climate and Forecast) conventions standardise how scientific data and metadata are stored in NetCDF files, ensuring consistency and machine readability. Looking forward to contributing and collaborating with the community to shape its future! 🌍

“Mesh data represents an unstructured grid that can include temporal and other components. It consists of vertices, edges, and faces that form a spatial structure in 2D or 3D space. Each vertex can store multiple datasets, which can also have a temporal dimension, making mesh data highly versatile for various applications such as meteorology, hydrodynamics, and environmental modeling…
This course is designed to equip you with the knowledge and skills needed to effectively work with mesh data within the QGIS environment…"

🌍 Heading to the 2024 CF Workshop in Norrköping, Sweden! 🇸🇪 CF conventions are vital for ensuring data adheres to the FAIR principles. While NetCDF files are great, CF standards make data truly interoperable across disciplines.

I'll be sharing ideas on introducing CF to new disciplines like biology and geology, helping them unlock the full potential of their data. Excited to learn how CF conventions evolve and meet the community! 🌟

Having one of those 3:22 in the a.m. moments when I got "stuff" to work!

Also, ugh, dealing with libraries reading hierarchical (grouped) datasets and having to deal with unnamed dimensions. Also, ugh, again.

Day six of the sixth eruption near and the town of This eruption is the largest one yet. Here is a 4-day series of satellite data from the instrument showing the mean amount of SO₂ in a vertical column of atmosphere (Dobson units). With time this will turn into sulfate particles forming volcanic smog.

This level 3 data is made available by The German Aerospace Center as files and can easily be opend in and visualized with MDAL library.

@roadskater
1) #netCDF is so much better than the individual formats thousands of scientists have made up over the decades. But I really wish people would use the metadata fields consistently (or at all).

2) Have you discovered IrfanView? It’s mostly just a viewer, but it handles every image type and many grid types that I’ve thrown at it. It is great for checking whether the netCDF shows what it’s supposed to.

The person who pinged me about this won't look too good dealing with the data product developers on his end if he keeps arguing for standards that, e.g., mean my software can read and plot the data. But forget moi, CF rules!

Otherwise. Ooof. My bad.

Roadskater, Ph.D.roadskater

Meanwhile, other software packages apparently can plot this stuff? I guess they have multiple coders, and funding to pay them all?

Otherwise, crud. The data grid mapping issue is a pain, but I figured that out. But… the data are in a structure, which… the library doesn't handle well (cough, gag) and disaster ensues.

There could be a career in sci software dev here. If one had the funding.

Spent some time the last few days examining whether I need to blow up and rewrite code in order to plot a satellite data product. Seemed from perusing a very necessary library API that it wouldn't need much work. On re-read, maybe more work. Sigh, now realizing that the API itself would need refactoring. Which, 1) their developers might say no, or 2) worse, they might say yes but they have SO many other demands.

The user who pinged me about this will probably be less than surprised. F!
