An intern on SWOT showed me a preliminary version of this earlier this week, even cooler to see it plotted against the NOAA tsunami forecast model!

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

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.

I was just looking for something like this for a motivated high school student, is the AAS copy equivalent to the free copy up on prappleizer.github.io by the same author?

National Climate Assessment Authors Are Dismissed by Trump Administration The Trump administration told researchers it was “releasing” them from their roles. It puts the future of the assessment, which is required by Congress, in doubt.

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. 🔭🧪

We got so busy I forgot to follow up, our team did amazing and we were recognized with the Rising All-Star Award! I'm very proud of everything we accomplished despite the challenges, from our first swerve year to the wildfires. #firstrobotics #frc

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

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.

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!

This is incredible, I can only speculate that it got a circular mask to fill/replace and it went to "Bitcoin" for whatever reason. How many Bitcoin stock images are they training on???

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

Three visualizations of an AVIRIS-NG scene. a) An RGB scene with clouds in the left and middle. b) A falsecolor scene that highlights the presence of clouds. c) A cloud mask overlaid in red over the RGB. It masks most, if not all, clouds present in the scene.

Finally, we think we have the beginnings of an instrument agnostic model for imaging spectroscopy. Here's SpecTf trained only on #EMIT, an orbital instrument, detecting clouds on #AVIRIS-NG, an airborne instrument with a different spectral grid. Exciting!

A plot with "wavelength (nm)" on the x-axis and "Attention Score" on the y-axis. A higher attention score indicates that the model thought the wavelength was more important for the cloud detection task. Some wavelengths are annotated: O2-A, H2O, and CO2. These are known absorption spectrums that SpecTf has learned from the data alone.

These are known absorption spectrums that SpecTf has learned from the data alone.

SpecTf's attention weights are interpretable - the model learned O2-A, H2O, and CO2 absorptions, all physically relevant for cloud detection. Look at how smooth these features are! Treating the spectra as a sequence instead of image channels or independent features is critical.
