From Stratosphere to Space: The hidden impacts of SSWs on Equatorial IT anomalies

This research investigates how sudden stratospheric warmings affect the coupling between the Equatorial Thermosphere Anomaly and Equatorial Ionization Anomaly using GOLD and GRACE-FO data.

What does the Variability of Earth's Highest Clouds Tell Us?

Polar Mesospheric Clouds form in a unique environment found only in the polar summer. PMCs are sensitive to any factors affecting polar mesospheric temperature and water vapor, such as Inter-Hemispheric Coupling (IHC), Solar Proton Events (SPEs), thermal tides, global climate change, etc., making these clouds an excellent tracer of polar atmospheric dynamics and coupling effects.

Interannual and Diurnal Variability of PMCs Using 10 years of Lidar and 14 years of CIPS Observations at McMurdo, Antarctica

This award-winning poster presents research on the interannual and diurnal variability of Polar Mesospheric Clouds (PMCs) using a decade of ground-based lidar observations and 14 years of NASA's AIM satellite CIPS data from McMurdo Station, Antarctica. The study investigates the occurrence statistics and correlations with solar cycle and polar vortex effects.
