I harvested this 572.8 pound giant today with the help of awesome neighbors and friends! 34 days until it's carved on Halloween!

In 4 weeks the smallest pumpkin in my patch has gone from an estimated 4 to 390 pounds and is now the largest. Dry weather is holding things back some, but it's still been a decent growing season.

We're a few days into this year's STORM (student training for observation research in meteorology) program up on Beaver Island in northern Lake Michigan. So far, we've had beautiful and calm weather that allowed for clearly defined convergence on the island.

It's been another great summer for fieldwork! When home, I've been working on another type of field work - growing my giant pumpkins! Introducing this year's patch of friendly (soon to be) giants: Hagrid, Sweetums, and Fezzik. Current estimated weights range from 8 to 23 pounds, but that'll change!

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕
A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

Hi everyone! With the abstract submission deadlines for the 2026 AMS Madison Joint Summit coming up, wanted to advertise these student award and travel opportunities available via the AMS WAF/NWP conferences. Feel free to spread the word to any interested students!
Weather Analysis and Forecasting / Numerical Weather Prediction Conference Student Travel Grant Awards

Student presentations selected as part of the 34WAF/30NWP conferences have the option of being judged, with a $50 award going to the top 3 oral and poster presentations in each conference (12 awards total). 

Also, once abstracts have been submitted, the WAF/NWP committee will offer three $375 travel grants to students whose abstracts have been accepted. 

Students who wish to be considered for a travel grant must send the following documents to the program chairs (austin.coleman@noaa.gov, john.lind@noaa.gov, jbravo2@stevens.edu, and tomer@windbornesystems.com) no later than Friday, April 3rd, 2026:
Statement of why they wish to attend the WAF/NWP conferences
- Statement of commitment to attend if they receive the travel grant
- Letter of support from their advisor
- Ensure that you have submitted an abstract to the WAF or NWP conferences before the abstract submission deadline

I just submitted my letter to NSF responding to its proposal to dismantle the National Center for Atmospheric Research (NCAR). I argue that doing so would be an astonishing and avoidable misstep, and that federal support for the institution should in fact be *increased.* [1/4]
Page 2 of letter by Daniel Swain. It begins: constructive suggestions regarding how the already remarkable institutional efficiency and societal impact of NCAR could be further enhanced through increased (not decreased) federal support in the years to come.
Please note: To ensure the highest level of technical rigor, this response focuses exclusively on the core atmospheric and natural hazard science topics within the author’s primary domain of expertise; for this reason, I have omitted a response to Topic 4 (Space Weather)."


NCAR weather modeling and atmospheric observing capabilities
a) Management and operations of weather-related observational platforms, modeling and science as a stand-alone activity.
The proposed management of weather-related research as a stand-alone activity is a scientifically regressive path that ignores the fundamental physical reality of the Earth system. Modern atmospheric science has demonstrated (largely, it is worth noting, due to groundbreaking researcPage 3 of letter by Daniel Swain. It begins: b) Management and operations of weather-related observational platforms, modeling and science as combined with other NSF investments/facilities.
The highly specialized nature of the NCAR-Wyoming Supercomputing Center (NWSC) infrastructure represents an extraordinary value proposition that cannot be replicated by combining it with more generalized NSF programs. The NWSC is not a generic high-performance computing (HPC) facility; it is a laboratory uniquely optimized for atmospheric science workflows, with a hardware and storage architecture specifically designed to handle the massive, high-bandwidth data demands of Earth system modeling. Furthermore, its model of providing an excellent, free-at-point-of-use technical support team ensures that the focus remains on the science rather than the overhead of systems administration. This centralized expertise allows individual researchers, smaller labs, and even entire universities—who would otherwiPage 4 of letter by Daniel Swain.

a/b) Ownership of the NSF NCAR Mesa Lab building for public and private use.
Far more than just an office building, NSF NCAR Mesa Lab is an iconic and purpose-built facility designed specifically for the study of atmospheric science. Its position at the physical interface of the Rocky Mountain foothills and the Great Plains is a deliberate reflection of its mission, serving as a visible symbol—in an iconically American setting—of the federal government's enduring commitment to science in service of society. For many in the field, including myself, the Mesa Lab holds singular importance as a focal gathering point for the global atmospheric science community. My own early career exposure to weather and Earth system modeling, in fact, occurred within these walls, and I have long felt that the facility’s architecture and location inspire a necessary sense of awe regarding the atmosphere’s complexity aPage 1 of letter by Daniel Swain. It begins: Dear Acting Director Stone and the NSF NCAR restructuring team:

I am writing to provide a formal response to the Request for Information (RFI) regarding the proposed restructuring of the NSF National Center for Atmospheric Research (NCAR) and its critical weather science infrastructure contained within the January 23, 2026 Dear Colleague Letter (DCL) entitled “NSF Intent to Restructure Critical Weather Infrastructure.” I submit these comments in my professional capacity as an atmospheric research scientist within the University of California, where my research focuses on the physics and dynamics of atmospheric processes related to extreme weather events and their role in shifting natural hazard and disaster risk.

My perspective is informed by a public-sector career dedicated to bridging the gap between fundamental atmospheric research and real-world application in an academic context, with a particular focus on understanding and mitigating

What so many seem not to understand is that if you start breaking everything into separate entities, you lose any efficiency and additive benefits you had by having them all as a single NCAR. It's worse than shooting ourselves in the foot. It's significant amputations when there's no infection.
