👏 The 2026 Heliophysics Summer School continues in Boulder, CO! A special shout-out to our deans, speakers, and leadership: Marco Velli, Farzad Kamalabadi, Hanne Mauriello, Amitava Bhattacharjee, Madhulika Guhathakurta, Nicholas Gross, Thomas Bogdan Cindy Bruyere, and Andres Munoz-Jaramillo!

🔭 The NASA Heliophysics Summer School has been going wonderfully and continues into next week. Besides lectures and labs, the students had a wonderful tour of the NSF's laboratory and explored the organization's celestial history. https://heliophysics.ucar.edu/summer-school

🎊 ☀️ The 20th Anniversary of the NASA Heliophysics Summer School was a great success with a wonderful panel discussion, and this year's class has kicked off! Welcome, research students and esteemed presenters. https://heliophysics.ucar.edu/summer-school

🎉 APPLICATIONS are OPEN for the 36th cohort of the Climate and Global Change (C&GC) Postdoctoral Fellowship Program!

This two-year fellowship is for early-career PhDs ready to help lead the next wave of climate and global change science. Fellows are paired with a mentoring scientist at a U.S. university, research institution, or federal agency to pursue research at the intersection of Earth system science, energy, decarbonization, and the human dimensions of a changing climate.

We're looking for applicants across the full spectrum of disciplines — from physical and biogeochemical sciences to social and integrated sciences — whose work advances our understanding of climate variability and change, strengthens Earth system modeling, or explores how communities and institutions navigate low-carbon, climate-resilient futures. Interdisciplinary applications are welcome.

Fellows join as UCAR employees with a fixed annual salary, full benefits, and support for relocation, travel, and publications. If you're finishing a PhD and want to spend the next two years doing research that matters, at the institution of your choice, working alongside a mentor in your field — we'd love to see your application!

🎯 DON'T MISS tomorrow's CPAESS Discovery Seminar with Waqar Younas, NASA Jack Eddy Postdoctoral Fellow on Wednesday, July 22, 2026 at 11:00am MT (Virtual), who will be speaking on "Ionospheric Irregularities and GPS Positioning Errors Over CONUS: What Recent Storms Reveal About Mid‑Latitude GPS Vulnerability." https://cpaess.ucar.edu/news/cpaess-discovery-seminar-waqar-younas

🎉 ☀️ We are thrilled to celebrate the 20th Anniversary of the NASA Heliophysics Summer School! This amazing cross-disciplinary program gave birth to a whole set of textbooks, video recordings and lesson plans (free for all); the NASA Jack Eddy Postdoctoral Fellowship; the Eddy Symposiums; and gathered together the next generation of heliophysicists from across the globe. Congratulations to and the many brilliant minds who worked tirelessly to make this come into being and sustain it for so long! https://heliophysics.ucar.edu/summer-school

📰 🌦️ We are delighted to see CPAESS Senior Scientist Kim Klockow McClain, who works with the National Weather Service, interviewed for her expert insight for this AP article about weather forecast apps!

☀️ 📖 Congratulations to our NASA Jack Eddy Postdoctoral Fellowship Alum, Robert Jarolim, and his new publication on "SuNeRF-CME: Physics-informed Neural Radiance Fields for Tomographic Reconstruction of Coronal Mass Ejections." This paper reconstructs phenomena from hybrid sparse observations and uses physics-informed methods to complete a model that then enables accurate forecasting, counterfactuals, and reasoning.
