Excited to announce Groundsource - an open-source dataset of historic flood events! This has easily been one of the coolest projects I've worked on recently! Thread 🧵 for details and all relevant links. 1/n

I present the most interesting graph ever made. HUMAN ON BICYCLE beats every other living thing. www.scientificamerican.com/article/a-hu...

Interesting read and something I have been thinking about recently. How fit is our education system for the new era and what does this mean for _learning_ (especially learning to learn), if students/pupils over rely on LLMs. What does this mean for my kids (2nd grade and kindergarten)...?

Some updates on NeuralHydrology and I'll also use this opportunity to give a shout-out to @gauchm.bsky.social for his continuous support and maintenance of NH

Are you working in large-sample hydrology? If so, we invite you to submit an abstract to our session for EGU 2026: HS2.4.2 "Large-Sample Hydrology: Advancing dataset developments, enhancing process understanding, and unifying insights through catchment modeling"

For those of you who are still undecided.

We (wife, 7 y/o, myself) spent New Years Eve playing "Stuffed Fables" boardgamegeek.com/boardgame/23... My wife's first roleplay game and also the most complex game we played so far with our oldest. Time was flying and we only made it to the start of the second chapter 😅

Hydrology Paper of the Day @kratzert.bsky.social on integrating water quality observations into the Caravan dataset: the need for proper metadata and processing of observations; a new river network with water quality stations; catchment delineation; and validation and flagging of suspect data.

Interesting point. I've been thinking about this as well in the past and I think, especially with ML, we have the opportunity to optimize for what we really want to know from the model, instead of training it on some proxy task

since everyone in Brazil's lost Twitter, I'm gonna try to make sure anything I post there is posted here too 🥲 here's a free building game I shared there a few weeks ago! mattstark.itch.io/tramstertram

the success of the user-created For You feed while the official Discover feed flops is actually a pretty major win for Bluesky — it literally is the embodiment of their goal to decentralize feed generation and give users more control/autonomy

Kid #2 got sick in time for Christmas and it seems I caught whatever he has, too. For the last three years we had at least one kid sick at Christmas. Happy Holidays 🎄

Excited to unveil Caravan-Qual! 🌊 We've expanded the Caravan framework to bridge the gap between water quantity and quality. This new open dataset features: 🔹 ~70M observations 🔹137k stations 🔹 100 constituents 🔹 Linked streamflow, forcing & attributes Links in 🧵

@rarakihydro.bsky.social leads an exiting new preprint that maps dominant hydrologic processes across >14k US watersheds using streamflow signatures + ML. It’s been such fun following Ryoko and Hilary’s leadership alongside Admin, Anne and Gemma. egusphere.copernicus.org/preprints/20...

It is so wild how all academics seem to have decided that LinkedIn is the new platform. Essentially the same announcement receives 100x the engagement.. On a job market platform. In the good old days of Twitter, this was different and it's kinda sad that not more researchers decided to join BlueSky

First time in years that I won't attend #AGU Inspiring week for everyone who attends and I hope you all stay safe.

This looks amazing 😲 Deserved first bookmark on bluesky

Back by popular demand: At #EGU26 we'll organize another BUGS session: Blunders, Unexpected Glitches, and Surprises! Submit abstracts on ideas that seemed great but didn't work, errors and bugs that led to new insights (or funny stories), or any other unexpected results. www.egu26.eu/session/56997

Quick shout-out for an #EGU26 session that I'm not involved in but think is worth sharing: EOS4.4 BUGS: Blunders, Unexpected Glitches, and Surprises For a detailed session description, see www.egu26.eu/session/56997

What do people do when their taxi driver is a) speeding like crazy and b) interacting with his phone all the time while driving. Not sure if I'm unlucky but this happens 4/5 times to me when taking the airport taxi back home...

It has been a while since the last news from Caravan but I'm happy to announce that a new extension has just been published. Caravan-CZ, a dataset curated by CHMI itself in cooperation with Grey Nearing. For details check: github.com/kratzert/Car... All extensions: github.com/kratzert/Car...

The paper is finally published and we were able to keep the original title. hess.copernicus.org/articles/29/...

jax.config.update("jax_debug_nans", True) saved my day.

Oh my god, I finally was able to fix it. After effectively not using my private laptop for the past 9 months (I have a corp laptop and a private desktop PC that runs Linux), I sat down and ask Gemini for help. I know, I know... Thread for details.

This has easily been one of the most interesting external meetings in a while.

i wrote about atproto and why it matters

Wow, ATProto (the tech that powers Bluesky) is pretty neat! If, like me, you have not read about it but were curious, this is a great read explaining how it works: overreacted.io/open-social/

Looking forward to a full day of exciting talks at the GRIT workshop in Oxford.

I just learned that the recording of my invited plenary keynote talk at #EMS25 last week in Ljubljana, Slovenia is publicly available. Here is the link in case anyone wants to watch it: vimeo.com/1118021056?f...

After about one year in review, the dataset paper for the Caravan-GRDC extension was finally published. See: essd.copernicus.org/articles/17/... I am so happy that GRDC was open for this effort and made some of their data freely available through Caravan.

I got tired of mashing together tools to write long threads with 𝐫𝐢𝐜𝐡 𝑓𝑜𝑟𝑚𝑎𝑡𝑡𝑖𝑛𝑔 and ℳα†ℏ—so I wrote La𝑇𝑤𝑒𝑒𝑡! It converts Markdown and LaTeX to Unicode that can be used in “tweets”, and automatically splits long threads. Try it out! keenancrane.github.io/LaTweet/

A packed room full of young and motivated scientists, today at my presentation at the @ellis.eu #SummerSchool2025. It was a real pleasure being there. Now I'm on my way back to Vienna but not without the by-now normal delay of 1h+ with the @bahn.de...

Never managed to attend a summer school during my master or PhD program. But it is never too late =) Arrived in Jena to attend "ELLIS Summer School: AI for Earth and Climate Sciences" and to give a talk later this week. Looking forward to many exciting conversations with young scientists

@simonwillison.net have you seen that?

Happy to share that if you are interested in large sample hydrology datasets and specifically water quality data you can now check our now officially published dataset: doi.org/10.1038/s415...

@leaflet.pub is such an innovative platform If you select some text (1), a tooltip appears that allows you to share the selection as a quote on Bluesky (2) If you click the Quotes icon (3), a panel showing all quotes appears (4) It's a terrific integration between blogging and microblogging

Oh, I didn't know. That is indeed pretty neat.

Das kann doch kein zufall sein @geschichte.fm ?!

We are in the year 2025 and people write a paper showing that a model trained with ‼️global, coarse resolution forcings‼️ performs worse in ‼️ungauged‼️ basins, than a regional model trained with ‼️local, high resolution forcings‼️ in ‼️gauged‼️ basins. This is used to say "training on more basins is bad"🤯

You know this feeling, when you get to review a paper for the n-th amount of time (always resubmissions to different journals after rejections), with the authors not adapting any of the comments and keeping all the obvious non-sense? Nobody ever should see my first draft of review comments.....

Interesting take: www.dlib.org/dlib/october...

I wish my universities would have offered such classes. Sounds amazing

@gauchm.bsky.social and @danklotz.bsky.social you are not alone

Trying to install Ruby and RVM on Linux for 15 minutes and wondering if there is really something more complicated than setting up Python.

Recommended read for the weekend: Sepp Hochreiter's book on AI! Lots of fun anecdotes and easily accessible basics on AI! www.beneventopublishing.com/ecowing/prod...

I just got made aware that a talk I gave recently at the @csdms.bsky.social meeting in Boulder is available online. Similar to my EGU medal lecture, the focus here was mostly on the conceptual similarity between LSTMs and classical rainfall runoff models: www.youtube.com/watch?v=ShTA...
