It's great to see the big crowd here in Boulder for the UCAR Members Meeting. I will be at the CISL booth during the reception this evening, so please come say hi and learn more about all the AI work we're doing at NSF NCAR.

Environment Canada and ECMWF have been testing this by using the AI model to nudge the larger scale features of the physics models. It does provide similar track performance to the AI model with better intensity.

Extremely excited to announce that I am the incoming chair for the AMS AI STAC Committee! Looking forward to leading our committee alongside @zhonghuazheng.bsky.social and @tropmetpie.bsky.social

We are seeking new members to join the AI STAC, including both regular and student members.

Screenshot of the lesson, showing a radar dish overlaid with text: 
"Online Course
Dual-Polarization Fundamentals
1h 30m - 2h
Description
Once an experimental type of weather radar, dual-polarized (β€œdual-pol”) weather radar is now deployed across the United States and many parts of the world. This lesson will introduce the basic principles of dual-pol weather radar. By the end of this lesson, learners will understand physical meanings of several commonly used polarimetric radar variables, including differential reflectivity, correlation coefficient, differential phase, specific differential phase, and linear depolarization ratio. Examples will be presented demonstrating the distinctive polarimetric signatures of different scatterer types, both meteorological and non-meteorological. Note: This lesson has as a prerequisite the prior lesson, Weather Radar Fundamentals. It is strongly recommended that beginning learners complete that lesson before starting this one."

Convenience AI
Sabina Leonelli & Alexander Martin Mussgnug12
Abstract: This paper considers the mundane ways in which AI is being incorporated into scientific
practice today, and particularly the extent to which AI is used to automate tasks perceived to be
boring, β€œmere routine” and inconvenient to researchers. We label such uses as instances of
β€œConvenience AI” β€” that is situations where AI is applied with the primary intention to increase
speed and minimize human effort. We outline how attributions of convenience to AI applications
involve three key characteristics: (i) an emphasis on speed and ease of action, (ii) a comparative
element, as well as (iii) a subject-dependent and subjective quality. Using examples from medical
science and development economics, we highlight epistemic benefits, complications, and drawbacks
of Convenience AI along these three dimensions. While the pursuit of convenience through AI can
save precious time and resources as well as give rise to novel forms of inquiry, our analysis
underscores how the uncritical adoption of Convenience AI for the sake of shortcutting human labour
may also weaken the evidential foundations of science and generate inertia in how research is
planned, set-up and conducted, with potentially damaging implications for the knowledge being
produced. Critically, we argue that the consistent association of Convenience AI with the goals of
productivity, efficiency, and ease, as often promoted also by companies targeting the research market
for AI applications, can lower critical scrutiny of research processes and shift focus away from
appreciating their broader epistemic and social implications.

5. Today I read a paper by @sabinaleonelli.bsky.social and Alexander Mussgnug that I think illustrates this point perfectly.

Cloning Came to Polo. Then Things Got Truly Uncivilized A polo legend and a businessman joined forces to copy the player’s greatest horse. But with a single clone worth $800,000, some technologies are a breeding ground for betrayal.

Wired just had a wild article about clones of top polo horses and a partnership gone wrong involving selling a cloned horse to a Russian oligarch. www.wired.com/story/clonin...

NSF’s actions violate the Preliminary Injunction. Though there may be situations where
a β€œtermination” and β€œsuspension” are not the same thing, there is no principled difference
between a β€œtermination” and the immediate, indefinite, and β€œfinal” β€œsuspension” of funding in
this context. The suspensions have the same effect, and are based on the same type of deficient
explanations, as the original terminations. NSF communicated the suspensions by means of a
form letter that failed to provide the requisite grant-specific reason for halting funding, and that
failed to adequately consider grant-specific interests, including the reliance interests of the
researchers. Therefore, pursuant to the Preliminary Injunction (Dkt. No. 55), NSF’s suspension
of the grants at issue here is VACATED. For avoidance of doubt, the Court also clarifies that
grant β€œtermination,” as the term is used in the Preliminary Injunction, encompasses
circumstances where grant funding is cut off on a long-term or indefinite basis, like the
suspensions carried out by NSF on July 30

🎀 BOOM: Federal judge just ruled to *reinstate* the suspended ~300 NSF grants at UCLA.

Determines that NSF violated the previous court order by attempting to swap "termination" with "suspension".

Automation bias is certainly a concern, and Snellman (1977) warned of a meteorological cancer from over reliance on automated guidance. The massive improvements in models and observations have outweighed any deskilling for now, but deep AI integration could be a problem.

NOAA, NWS, and NASA funding is included in the Commerce, Justice, and Science appropriations bill. NOAA and NSF get minor cuts, and NASA gets a slight increase. The House version of the bill cuts NSF by 20% but keeps NOAA and NASA flat. Both have passed appropriations committees but not chambers.
