Working with a data file like this (in Excel) is why data cleaning is often underappreciated.

Finally get it working again. Hopefully it would be useful for ongoing C++ project development.

The preprint for our paper is now up at arXiv: arxiv.org/abs/2505.06484
Hopefully it'll help people who are forced to leave. Still good advice for researchers, in general.

This seems to be a good approach to track manuscript review status. JOSS also has a GitHub based review process.

17.04.2025 04:38 — 👍 0 🔁 0 💬 0 📌 0This semester I gave a couple of lectures to the graduate students in University of Houston on water science. I was astonished to find out that several students are very interested in #DGGS #DGGRID for hydrologic research. The Q&A session was filled with in-depth discussions.

It literally took us five years to acknowledge that we need a better mesh for #landsurfacemodel. Regional refinement mesh for #LSM can be both efficient and effective for many scientific discoveries and applications. #ESS #PIMeeting #DOE
