As the cover paper in the recent #VZJ issue, along with in-depth discussion among project members, this work further amplified the decadal challenge in soil representation and ecosystem productivity in LSM. acsess.onlinelibrary.wiley.com/toc/15391663...

Our recent paper explores a few factors that may be important when LSM moves towards kilometer scale: doi.org/10.1016/j.jh... #mesh #data #lsm

My #AGU poster in animation. youtu.be/i0cGuaZR9Yg?...

Next generation Earth system models such as #E3SM should be able to represent large #river #Delta. #AGU25

In this year's #AGU, I will present the first global-scale unified #MPAS mesh framework for kilometer-scale two-way coupled land-river-ocean simulations. #RRM #km-esm #E3SM

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. Visualization powered by #GeoVista #PyVista

Improving the representation of plant water stress and water use in Earth System Models Dukes et al. @dukesjeff.bsky.social @changliao.bsky.social @richphillipslab.bsky.social @scottmcadam.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/...

E3SM all hands meeting takeaways: Models are moving towards km-scale, even with AI/ML.

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

Data science might be one of the most overrated science because literally no science can get away without data.

"The unified Model for Prediction Across Scales (MPAS) grid to cover all model components on the Earth’s surface.". We finally made the unstructured mesh framework into #E3SM v4 goal. #ESM #mesh #grid #RRM e3sm.org/e3sm-plan-fo...

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
