Coverage of our recent work about impact of increasing greenhouse gases on geomagnetic storm effects in the future (2025/08/25)
Recent work from Prof. Liu and Dr. Pedatella has revealed interesting results regarding how increasing CO2 would modulate the space weather impacts in the future. Their research revealed that geomagnetic storm impacts will become more severe for satellite users and operatures, as the storm effects will be more dramatic in terms of relative changes.
Published online in Geophysical Research Letters on May 30, 2025, this paper has received much attention from the public. Here are links from CNN, Astronomy.com, National center for Atmospheric Research, Kyushu University.

Prof. Liu's feature in Kyushu University Science Salon (2025/06/25)
Recently, Prof. Liu was featured in Kyushu University Science Salon, explaining the importance of space weather in the modern world. Be sure to check out the full interview below!
Continued coverage of our recent discovery of Es intensification caused by Geomagnetic Storm (2025/06/25)
Recent work from Prof. Liu and our Assistant Prof. Qiu has made a groundbreaking discovery regarding the enhancement of sporadic E (Es) layers during major geomagnetic storms. Their research revealed that Es layers, which can adversely affect shortwave communications, become significantly enhanced during geomagnetic disturbances.
Published online in Geophysical Research Letters on April 23, 2025, this study demonstrates the importance of space weather information for the safe operation of aviation control and maritime communication systems that use shortwave radio waves, as Es layer enhancements can disrupt normal communications. Summary of the work can be found here.
Not only featured in the Kyushu University press release, our work has also gained some attention on the web, with coverage from space.com and eurekalert.org, exposing our lab's research to the general public.
Visit of Dr. Yosuke Yamazaki (2025/01/30)
Dr. Yosuke Yamazaki (GFZ, Germany) who is on a short term visit until late February, gave us a talk on his recent work on Sq (solar quiet). If you have any questions about his work, or just wanted to know what it feels like to be a scientist (FYI, he's also a Kyushu University alumni), feel free to visit Dr. Yamazaki while he's here!
Visit of Dr. Jia Yue (2025/01/20-2025/01/23)
On the week of January 20th, we got a brief visit from Dr. Jia Yue (NASA Goddard Flight Center, US) on an outreach mission by presenting to us his grueling work on the overall coupling of thermosphere and ionosphere. Later after presenting his work, some of us went jogging with him and Huixin-sensei to the beach for bottomless oysters!
