Finally, our ML methane plume detection work is published in RSE! This took a while so we already have some newer, better results we hope to share very soon. doi.org/10.1016/j.rs...

Catching up on pubs: as a follow-on to our Euclid work, we showed that diffusion models can simulate galaxies quickly and accurately for Roman weak lensing measurements. Hopefully we can continue this work with newer conditional methods and recently released catalogs. doi.org/10.3847/1538...

Couple months late but still wanted to share, Team 2404 earned its first blue banner since its rookie year in 2008! Huge thanks to our alliance 7415 and 6995, couldn't have asked for a better first year in California Districts.

Following up on this, here's an even cooler animation of the SWOT overpass! earthobservatory.nasa.gov/images/15466...

Excited to try this out! Earth foundation models have frankly been hit-or-miss, but this seems promising. deepmind.google/discover/blo...

Our EMIT cloud mask work is published in PNAS! This is my first major first-author publication ☁️🌎🛰️ www.pnas.org/doi/10.1073/... Just in time, we're releasing an improved model to be used for our new data product: github.com/emit-sds/Spe...

A friend just asked me what I do to stay hopeful and I told him one of my favorite strategies…I stay hopeful by remembering that no one has any idea what the fuck is going to happen, so as long as we don’t know, we gotta do what we can.

Congratulations to @columbiaseas.bsky.social and Columbia Space Initiative (SEDS) on a successful launch and recovery of the first US student-led LOX hybrid rocket!! As a board member of the founding class it's incredible to see how far we've come 🚀🚀 www.engineering.columbia.edu/about/news/c...

Breaking News: The Trump administration dismissed all the scientists working on the government’s premiere report on the effects of climate change in the U.S.

CGP Grey has taken "thumbnail optimization" very literally by applying common deep learning augmentation techniques to his older videos' thumbnails: color inversion, tile flipping, gaussian noise... It's certainly working, I myself absentmindedly clicked on one.

New preprint! We use generative diffusion models to quickly produce realistic #Euclid -like galaxies, a step towards addressing challenges in calibrating and validating weak lensing analyses. 🔭🧪 arxiv.org/abs/2504.07183

Day 1, here we go! #FRC2404 #FRC #AVR

So excited to get our first complete swerve, vision, and kinematics stack working!!! I'm very impressed by how easy it was to build with the wpilib and photonvision APIs. Yes, the camera is mounted upside down. Shoutout to 980 for letting us use their field on weekends 🤖 #FRC #robotics

Whoa, this one hit hard and quick in Pasadena, not the rumble I'm used to. I thought a car hit the apartment building or something

there's a lot of things going on in the world right now (from asteroids to... more existential threats), but we're working really hard on getting some papers out ASAP just in case, and our FRC team is building a kick-ass robot, so I just have to keep going.

Apparently all the PhD researchers holding prestigious NSF-funded research fellowships are having their salaries withheld until some unspecified time when the leadership figures out how to eliminate any grant funding that doesn’t align with the president’s political ideology.

I'm very proud of presenting today the first article of my PhD student Nicola Nari, the confirmation of the existence of a Super-Earth in the habitable zone of the nearby Sun-like star 82 Eridani (HD 20794), originally proposed by Michael Cretignier a few years ago 🔭🪐

You fuckers are sleeping on Jupiter’s moons. I don’t want to ever hear one more person whine about Pluto if they can’t tell me a single fact about the in-every-way-superior Ganymede.

High-resolution airborne AVIRIS-3 L1b radiance is publicly available for the #LAwildfire via Earthdata, and visualized on MMGIS. Incredible imagery of burn extent. #remotesensing 🌎🛰️ popo.jpl.nasa.gov/mmgis-aviris... www.earthdata.nasa.gov/data/alerts-...

LAUNCH at 0703 UTC Jan 16 of New Glenn from Canaveral, with successful parking orbit insertion of stage 2. Stage 1 made its reentry burn but did not successfully complete landing on the barge. Stage 2 is due to restart to go to higher orbit. Congrats Blue Origin!

Valorie's been my side project for about a year now, it's a #Discord bot that sends notifications for #Valorant #VCT #Esports. I just added a Pick'Ems feature so you can compete with your friends, check it out! www.reddit.com/r/ValorantCo...

Many of you know Michele Judd—the former director of the @caltech.edu Keck Institute for Space Studies (KISS). She’s supported lots of studies that have changed planetary science. She and her family lost their home in Altadena this week in Eaton fires this week. Consider donating. gofund.me/0ce9bbd9

via Director Laurie Leshin: #Caltech #JPL has established a Disaster Relief Fund to support our colleagues and students affected by the #EatonFire and #LAfires. Over 150 JPLers have lost their homes so far. Please consider contributing. caltech.imodules.com/controls/ema...

Our preprint on the Spectroscopic Transformer and all associated code and datasets are now available! SpecTf is a #deeplearning model specifically for imaging spectroscopy and #EMIT #remotesensing Preprint: arxiv.org/abs/2501.04916 Code: github.com/emit-sds/Spe... Dataset: doi.org/10.5281/zeno...

Standing by with bags packed tonight near downtown Pasadena. I'm so worried about my friends, coworkers, and students and devastated for our community. I hope to god everyone makes it through safely.

Policies have consequences. Methane emissions from the Permian region fell 26% in 2023. www.bloomberg.com/news/article...

My 3-week conference/holiday travel ends with a checked bag stuck in Kansas courtesy of Southwest 🙃 Just glad to be home.

Cool chart!

I had an awesome Friday afternoon (!) poster session at #AGU24. Thanks to everyone that stayed until the end, and I'm looking forward to another year of exciting collaborations.

Completely packed room here at #AGU24 Remote Sensing of #CH4 and #CO2 from Space: The Expanding Observing System! Should've upgraded us to a keynote hall 😅

I'll be honest, I cut it really close this #AGU24 - finally trained a viable model on Wednesday, made the poster from scratch on Thursday, printed it on Friday! Bless the JPL print shop, they're incredible.

I'm at #AGU24 next week! We're excited to share our new Spectroscopic Transformer for an improved #EMIT cloud mask (GC41H-0038, Thurs. poster) and preliminary #methane retrievals for anthropogenic plume detection (A53I-2209, Fri. poster). Come chat about deep learning for imaging spectroscopy!

Insanely honored to be part of this year’s Forbes 30 Under 30 in Science. It is also interesting to see them highlight some of the translational aspects of my past scientific research that I do not talk about as much on here! 🧵 below: (1/6) www.forbes.com/30-under-30/...

When you encounter information like this, what do you do? 🧪 A thread on science misinfo. This is a bold claim, one that stirs emotions, wonder and awe at nature. So when I see it, I'm immediately skeptical. I want to try and find a primary source. But I can't find any study to support this.

*deep sigh of relief* #ML

Rocks near the Mars Curiosity Rover this weekend on Sol 4379. Over eons of wind erosion and other processes, the softer layers were removed, leaving this.

Oh, yeah. It's all coming together. #FRC #Robotics

Oops, missed the start of #adventofcode ! I did the first few days of 2023 as python one-liners (many nested list and dict comprehensions), but this year I'm planning on taking this opportunity to learn Julia. Anyone else participating with challenges? adventofcode.com

I just tried the Quest 3 after owning a Vive Index for a few years, and I was very impressed by the optics! It's got me thinking about VR/AR data visualization again, now that you can actually comfortably read text...

Could I get a: There's no place like 127.0.0.1:8888/?token=js79j7...

Okay, I have to do a thread on this pretty amazing article because it is just seriously chockers with eye-opening stats about 'direct air capture' - ie, sucking up air and trying to remove carbon dioxide from it news.mit.edu/2024/reality...

Really looking forward to giving this a read, this will be an incredible resource for future science & data science collaborations!

Huge win from @franzanth.bsky.social creating a Content Scraper Blocklist: bsky.app/profile/cont... It's a blocklist for the kinds of engagement bait accounts that repost stolen content, often with misleading captions.

Wait, what year is it??? #FRC

Running into the imbalance problem with geospatial/remote sensing deep learning regression again - there'll be 1/1000 samples of outlier values that are 1000x larger than the median, and of course accuracy matters more at the extremes. Over/under sampling, weighted loss... any other common tricks?

This @theverge.com interview with Roland Allen about notebooks was amazing - at some point, David said about note-taking apps that "you try them all and you eventually just get a nice notebook and a pen and you start filling it" and I yelled YES THANK YOU in the car
