The Western United States MTBS-Interagency database of large wildfires, 1984–2024 (WUMI2024a) Abstract. Wildfire regimes of the western United States (US) have changed dramatically since the 1980s but our understanding of the causes and effects of these changes is limited by a lack of a qualit...

WULFFSS is an evolving project that we hope is a valuable contribution to forest-fire modeling.

Wildfire data are from WUMI2024a (Williams et al. 2025): doi.org/10.5194/essd...

Model code & training data are available in the "assets" tab: gmd.copernicus.org/articles/19/...

WULFFSS is an efficient, interpretable, monthly stochastic forest-fire model for the western United States that simulates the probabilities & sizes of large forest fires on a 12 km grid.

The model can be coupled to a forest-ecosystem model accurately model fire-forest feedbacks!

The Western United States Large Forest-Fire Stochastic Simulator (WULFFSS) 1.0: a monthly gridded forest-fire model using interpretable statistics Abstract. We developed the WULFFSS, a stochastic monthly gridded forest-fire model for the western United States (US). Operating at 12 km resolution, WULFFSS calculates monthly probabilities of fires ...

Our new manuscript by Park Williams et al. (2026) is now published:

Caroline, a postdoctoral scientist, stands in front of a replica of the NASA Mars Perseverance Rover, a six-wheeled robot that can drive on the Martian surface. In the top left-hand corner hanging from the ceiling, there is a replica of NASA's Ingenuity Mars Helicopter. Caroline is smiling, wearing a cool green with yellow stars button-up top and light blue jeans.

I'm Dr. Caroline Juang, and big news is I (finally) started my Postdoctoral Fellowship at NASA Jet Propulsion Laboratory in Pasadena, CA. Grateful to everyone who made this move possible.

I look forward to collaborating and sharing more research updates as I study California wildfires at JPL!

hi bluesky~ my name is tess, and i'm a climate scientist studying drought, fire, and climate variability and change! i recently defended my PhD on the climate dynamics that drive forest fire in the Western US at @lamont.columbia.edu and started as an NPP fellow at NASA GISS. excited to be here ❤

California's Getting an Earlier Start to Wildfire Season - Eos Human-caused climate change has pushed the onset of fire season in the state to as much as 46 days earlier than it was 30 years ago.

Wildfire season in some parts of California starts more than a month earlier than it did in the 1990s, according to new research. 🧪

Don't miss our new NASA Science spending and economic impact resource at dashboards.planetary.org/nasa-science.html — see space science spending in every state and congressional district and custom reports for each region. A unique resource.

Earth scientists are sharing their research for 100 hours in a nonstop livestream, b/c US funding for NASA and NOAA are at stake.
Many of my colleagues are organizing or presenting.

Advocate for US weather and climate!

Hour 33 is going strong! We have had an amazing line up of keynote speakers this evening. So much fun to watch! wclivestream.com/watch/

All probationary federal employees at NOAA’s EMC that’s responsible for keeping all US weather model systems running have been fired with 1 hours notice. And that includes me and colleagues. We will not go quietly because we care about the NOAA mission to protect the public.

Happy International Day of Women and Girls in Science! The future generation of STEM leaders starts with showing girls who they can become, and I'm proud to be showcased by my institution @lamontearth.bsky.social

Is there a link between #ClimateChange & increasing risk/severity of #wildfire in California--including the still-unfolding disaster? Yes. Is climate change the only factor at play? No, of course not. So what's really going on? [Thread] #CAfire #CAwx #LAfires iopscience.iop.org/a...

The Palisades Fire Is Raging under Santa Ana Winds—Here's How They Work The nature of the Santa Ana winds makes them perfectly suited to spreading flames. The destructive Palisades Fire is the latest example

Wrote a bit about the Santa Ana winds driving the Palisades fire, as well as the climate change context (with a huge shout-out to @weatherwest.bsky.social and his extremely informative livestreams) 🧪

Screenshot of the Watch Duty App at Thursday, January 9, 2025, at 8:48am Pacific Time. The screenshot shows the locations of the Palisades Fire, Eaton Fire, and Hurst Fire in Los Angeles, California.

The Watch Duty App has good information on evacuation zones for the #PalisadesFire, #EatonFire #HurstFire. app.watchduty.org

With Santa Ana wind gusts continuing through Friday, fires that ignite will spread rapidly across dry fuels. Please take care!
