We recently released the beta version of URaster on GitHub and PyPI:
github.com/changliao102...
and pypi.org/project/uras...
This package enables us to set up unstructured mesh-based hydrologic and land surface models.

10 quick tips for making your software outlive your job!
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.

This 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
