One more reminder about our open faculty position! We'll begin reviewing applications in a few weeks.

@agu.org has a tool to help you submit a comment to NSF on the importance of NCAR: agu.quorum.us/campaign/154... #SaveNCAR

Stop by our @ncar-ucar.bsky.social town hall at 12:15 today. #AMS2026 Check out: NSF NCAR’s Advanced Computing, Data Services, and New AI Ecosystem Road Map for Earth System Science @ 106th AMS Annual Meeting ams.confex.com/ams/106ANNUA...

Very exciting to share that @climatecentral.org is hiring a Climate Data Scientist to join a new climate services effort focused on advancing predictions of risks and hazards on seasonal-to-decadal timescales. The application closes on February 9, 2026 at 5pm ET, & the description can be found here:

The extreme cold across eastern N America is due to the Alaskan Ridge regime, which on average brings the coldest winter weather to this region. Is this happening more often? No. During the modern warming era, there has been no observed trend in the occurrence of this regime at this time of year.

NSF just posted their Dear Colleague Letter regarding the restructuring of NCAR. www.nsf.gov/funding/info...

“In short, the atomic ensemble time scale at our Boulder campus has failed due to a prolonged utility power outage. One impact is that the Boulder Internet Time Services no longer have an accurate time reference.” groups.google.com/a/list.nist....

14 two-year postdocs for academics of any nationality who cannot continue their research due to US politics. Do share if you know of such.

The Call for Proposals for #SciPy2026 is now live! pretalx.com/scipy-2026/cfp If you have questions about @scipyconf.bsky.social just ask and be on the lookout for proposal writing office hours!

Uhhhh, yikes ☹️ www.nsf.gov/news/intent-...

“The changes permit as few as one outside review rather than the current minimum of three, end the routine use of expert panels to discuss those individual reviews, and give program managers greater authority to recommend which proposals should or should not be funded.”

In case you want to share with your networks, this is a good article by the NYT on the broad scope of work done by NCAR and some of the key discoveries (e.g., microbursts and aviation accidents).

A great opportunity to learn and collaborate with folks on open geoscience workflows!

Heads up on this vital 100 hour streaming marathon on the value of weather and climate expertise as National Weather Service struggles with staff shortages and reduction in service www.forbes.com/sites/marsha...

Have you ever looked at a weather map online? Or seen a nice visualization of weather forecast model output? If so, NSF Unidata almost certainly made that possible in one way or another. Modern meteorological education would not be possible without the data, tools, and resources they provide.

If you or somone you know has been impacted by federal grant funding cuts, there is a funding initiative supported by the Alfred P. Sloan Foundation Kapor and William Grant Foundations that provides modest bridge funding. Please share widely. www.spencer.org/grant_types/... #science #openscience

BREAKING: NSF has frozen all grant funding, as of yesterday. It's unclear when they will resume funding awards, or why the pause has been put in place. www.nature.com/articles/d41...

🔔 Slides & recordings from the 2025 Improving Scientific Software Conference are now available within the online conference program: sea.ucar.edu/iss/2025-pro... Thanks to all who joined us—see you in 2026! #ISS2025 #ScientificSoftware

Great opportunity for Earth systems science data folks:

If you provide Earth system science learning at the post-secondary levels or within the workforce, we need your input! Take this quick survey so we can understand your priorities + obstacles to providing education, training & support: www.surveymonkey.com/r/ESS_Needs

I’m keeping a running upperair observation status page on my website. I have additional metadata like reason for degradation, degradation type, when the degradation began, etc. In a coming update you will be able to read those things by clicking on the site. www.stormscale.io/spc/upperair...

2 additional radiosonde sites are temporarily suspending launches, while 6 others are reducing to one launch a day. 14 out of 83 sites now have partial or no launches. The more radiosondes are reduced or suspended, the more noticeable the forecast skill reduction becomes.

Reminder, NOAA/NWS houses the Volcanic Ash Advisory Center. NOAA/NWS reductions in force (RIF) decisions are expected in the next few days.

Applications now open for the Climatematch „Computational Tools for Climate Science“ course! I am a big fan of Climatematch and recommend folks to apply if they want to start with climate data analytics (or help out as a TA!) portal.neuromatchacademy.org

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week. "...the birthplace of weather and climate forecasting"

For those who don’t know what NOAA’s Radar Operations Center (ROC) does, they are the tech experts who keep our nation’s weather radars running, 24/7. ROC has a hotline NWS offices can call for help getting broken radars working again quickly. www.roc.noaa.gov

Job opportunity for a Research Software Development to join my collaborators on the @rhodiumgroup.bsky.social Climate Impacts team (and collaborate with me!) www.linkedin.com/jobs/view/41...

I have written a short statement responding to mass firings today of #NOAA / National Weather Service (#NWS) staff (which were concentrated among recent hires as well as highly experienced staff who had recently been promoted). Please see below screenshot & below for full text.

Join us! Science Homecoming helps scientists reconnect with communities by writing about the importance of science funding in their hometown newspapers. We’ve mapped every small newspaper in the U.S. and provide resources to get you started. Help science get back home 🧪🔬🧬 🏠 sciencehomecoming.com

So much of what is happening is unacceptable, but this one hits me right in the gut. Sending love and support to all of my EarthScope friends and colleagues.
