The Role of High Energy Photoelectrons on the Dissociation of Molecular Nitrogen in Earth's Ionosphere
Srimoyee Samaddar, Karthik Venkataramani, Justin Yonker +1
Soft x-ray radiation from the sun is responsible for the production of high energy photoelectrons in the D and E regions of the ionosphere, where they deposit most of their ionizat…

Comparison of the Thermospheric Nitric Oxide Emission Observations and the Global Ionosphere-Thermosphere Model (GITM) Simulations: Sensitivity to Solar and Geomagnetic Activities
Cissi Y. Lin, Yue Deng, Karthik Venkataramani +2
An accurate estimate of the energy budget (heating and cooling) of the ionosphere and thermosphere, especially during space weather events, has been a challenge. The abundance of N…
