Studying Ionosphere Using SKA-Low and SKA-Mid
Abhirup Datta, Samit Kumar Pal, Sarvesh Mangla +4
The Earth's ionosphere introduces systematic effects that limit the performance of radio interferometers operating at low frequencies (\,GHz). These ionospheric effects…
Ionospheric responses over the Antarctic region to Intense Space Weather events: Plasma Convection vs. Auroral Precipitation
Sumanjit Chakraborty, Gopi K. Seemala
The present investigation is directed at exploring southern polar ionospheric responses to intense space weather events and their correlations with plasma convection and auroral pr…
Influence of ICME-driven Magnetic Cloud-like and Sheath Region induced Geomagnetic Storms in causing anomalous responses of the Low-latitude Ionosphere: A Case Study
Sumanjit Chakraborty, Dibyendu Chakrabarty, Anil K. Yadav +1
This work shows an anomalously enhanced response of the low-latitude ionosphere over the Indian sector under weak geomagnetic conditions (October 31, 2021) in comparison to a stron…
On the Low-Latitude Ionospheric Irregularities under Geomagnetically Active and Quiet Conditions using NavIC observables: A Spectral Analysis Approach
Sumanjit Chakraborty, Abhirup Datta
Ionospheric irregularities and associated scintillations under geomagnetically active/quiet conditions have detrimental effects on the reliability and performance of space- and gro…
