Ionospheric Response to the Coronal Hole Activity of August 2020: A Global Multi‐Instrumental Overview by Waqar Younas, Majid Khan, C. Amory‐Mazaudier, P. O. Amaechi

“…Abstract We have studied the ionospheric response to a coronal hole event of August 2020 using the data from global ionospheric maps, ground magnetometers and parameters from the instruments onboard SWARM and thermosphere, ionosphere, mesosphere energetics and dynamics satellites. The role of different physical drivers, responsible for observed ionospheric disturbance, has been identified. …”

Thermospheric Conditions Associated With the Loss of 40 Starlink Satellites by Yongliang Zhang, Larry J. Paxton, Robert Schaefer, William H. Swartz

“…Abstract We analyzed far ultraviolet data from Defense Meteorological Satellite Program (DMSP)/Special Sensor Ultraviolet Spectrographic Imager (SSUSI) and Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED)/Global Ultraviolet Imager (GUVI) and found significant changes in the thermospheric density and composition during the 3–5 February 2022 storm when 40 Starlink satellites started to re‐enter the atmosphere associated with increased neutral drag at an altitude around 210 km. …”

Thermospheric Neutral Density Data Assimilation System Based on the Whole Atmosphere Model During the November 2003 Storm by Ching‐Chung Cheng, Timothy Fuller‐Rowell, Eric K. Sutton, Tzu‐Wei Fang, Jann‐Yenq Liu, Daniel R. Weimer

“…The second were neutral density estimates from the Global Ultraviolet Imager (GUVI) limb‐scan airglow observations aboard the Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite. Due to the intensity of the November 2003 storm, two changes were necessary in WAM. …”

On the ionospheric response in the Taiwan region to Typhoon Meranti in September 2016 by Peng Chen, Mingzhu Xiong, Yibin Yao, Hao Chen, Fucai Tang, Liangcai Qiu, Yuchen Zhang

“…Still, background wind conditions restricted the propagation of gravity waves from the mesosphere to the thermosphere and led to TID predominantly concentrated between 06:00 and 13:00 UT each day.…”
