A Model of the Globally-averaged Thermospheric Energy Balance
Karthik Venkataramani, Scott M. Bailey, Srimoyee Samaddar +1
The Atmospheric Chemistry and Energetics (ACE) 1D model is a first principles based model that generates a globally averaged thermosphere and ionosphere in terms of constituent maj…
The Role of Solar Soft X-rays Irradiance in Thermospheric Structure
Srimoyee Samaddar, Karthik Venkataramani, Scott. M. Bailey
We use a new Atmospheric Chemistry and Energetics one-dimensional (ACE1D) thermospheric model to show that the energies deposited by the solar soft x-rays in the lower thermosphere…
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…
