The NextGen Water Resources Modeling Framework: Community Innovation at the Intersection of Hydrologic, Data and Computer Sciences Hydrologic science lacks a comprehensive theory of stormflow generation, preventing the development of a general hydrologic model. Studies show that models focusing on dominant local processes often ...

A new paper by Ogden et al. describes the framework of the NextGen National Water Model, which uses CSDMS technologies such as the Basic Model Interface (BMI).

Classroom with LSU students and a CSDMS instructor

Eric and I took the CSDMS Roadshow to Baton Rouge last week. We had a great time with great people at LSU! We also wrote a lot of code.

Fortran is the language of science! 🫠

The CSDMS GeoTiff data component has been updated to v0.4.0. Available on PyPI and conda-forge.

Join us in Boulder for a week of science && software!

I was kinda disappointed there wasn’t more on the ethics of resource use by gen AI.

YouTube video by CASS Community The state of AI for research software engineering

The CASS UDX webinar last week was interesting: "The State of AI Use among Research Software Engineers". People surveyed are “curious, but cautious” about generative AI tools, which mirrors my feelings.

Food lines were 2X normal this morning at the Weld Food Bank, which told me 2/3rds of their visitors said they were impacted by the SNAP food benefit freeze. Our microgiving campaign has raised $50,000 for Weld Food Bank so far. Even $5 helps: weldfoodbank.org/wordofthanks/

Software!!1! *shakes fist*

Starting in about an hour, at 10 am MST.

See you soon!

Registration is now open for the CSDMS 2025 Annual Meeting: "Exploring Earth’s Surface with Models, Data & AI". This year’s meeting is held at the University of Colorado Boulder from May 13–15. Registration and additional details, please visit: csdms.colorado.edu/wiki/Form:An...

Hope you can join!

That's right! Recordings are typically posted a couple days after the webinar date. You can view webinar recordings at csdms.colorado.edu/wiki/Webinars.

I'm looking forward to this upcoming (Thu Feb 13) CSDMS webinar by Daniel Shapero, "Docker, or, What to do When Software Has Betrayed You".

Daniel does cool science + software. I think this will be interesting and entertaining.

I’ve called my members of congress and asked them to fight the administration’s federal spending freeze.

Advertisement for the Earth Surface Processes Institute in a minimalist design with olive green curved shapes on cream background. Large bold text announces 'EARTH SURFACE PROCESSES INSTITUTE' at the top, followed by 'AT THE UNIVERSITY OF COLORADO, BOULDER EAST CAMPUS'. Application deadline of January 28 is prominently displayed in light blue text with a purple asterisk noting 'NOTE EXTENSION'. The dates 'MAY 5-12, 2025' appear in curved text. The image describes ESPIn as a six-day immersive training for 25 early career scientists, listing three main skills: numerical modeling, modern collaborative scientific software development, and use of open source community cyberinfrastructure. The CSDMS (Community Surface Dynamics Modeling System) logo appears in the bottom right.

🌎 ESPIn 2025: Where Earth science meets code! Learn Python modeling, work on team projects, enjoy a Boulder field trip & boost your career. Topics: Git, Landlab, HPC & more. May 5-12 at CU Boulder. Early career scientists apply by Jan 28! @csdms.bsky.social

When I left home at 8a, it was 26 F and windy on Shanahan Ridge, but -1.5 F and nearly calm at the Foothills Lab, which is about 5 mi away and 400 ft lower in elevation.

Temperature and dewpoint time series from the NCAR Foothills Lab, showing a jump in temperature around 10:30a.

The inversion trapping a puddle of cold air in Boulder Valley finally broke up, allowing winds just above to reach the surface.

A thoughtful scientist, luminescence wizard, ultrasupportive colleague, and someone who's made me laugh till I cry on numerous occasions—Harrison is so deserving of the prestigious PECASE award!

Everyone in Boulder is out running before the cold snap.

Back to work after a really good holiday break, and lots of exciting things happening already! It reminded me we currently have an open #ResearchSoftwareEngineer #RSE position in our #AdvancedResearchComputing group at the #RosalindFranklinInstitute. #Job

After a month of wrangling, I finally got an example model (written in Fortran, wrapped in Python through Cython, built with CMake and Meson, componentized in the CSDMS Python Modeling Tool, pymt) to build and run on Windows. I am so relieved!
