Her paper with cool new model validation results is out now: https://www.cambridge.org/core/journals/environmental-data-science/article/simulating-the-air-quality-impact-of-prescribed-fires-using-graph-neural-networkbased-pm25-forecasts/A93DD21899CA00208E0DE3F3B0C4DC3C18 Feb 2025 13:00 +0000at://did:plc:kffezjboigno7psswsq5qsyu/app.bsky.feed.post/3lihcxrx2xk2hhttps://bsky.app/profile/jatanbuch.bsky.social/post/3lgl3vqsql22jAlso consistent with my experience that PNAS is actually a terrible journal. I know of several PNAS papers that were either straight wrong or you could not reproduce their results.

Should we be more private sector focused in our collaborations while also doing more public outreach in non-university spaces?

So it felt good to have contributed something more physically motivated; here's a new algorithm we developed to simulate aerosol perturbations (or seeding) in PySDM: https://github.com/open-atmos/PySDM/releases/tag/v2.7517 Sep 2024 17:50 +0000at://did:plc:kffezjboigno7psswsq5qsyu/app.bsky.feed.post/3l4eldntxor2whttps://bsky.app/profile/jatanbuch.bsky.social/post/3kyec4nsidb2yAs the fire season intensifies over parts of the western United States, I wanted to share some results from ongoing work to improve seasonal and subseasonal-to-seasonal scale forecasts of wildfire frequency and burned area with machine learning.
