Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAS, has co-authored a paper titled Cross-equatorial travelling ionospheric disturbances and changes in background ionospheric densities over Indian longitudes during the geomagnetic storm of 20–21 December 2015, which has been published in Advances in Space Research. This study examines the ionospheric response over the Indian region during a space weather event in December 2015. Additionally, it tracks a propagating disturbance in the ionosphere that originated in the Australian sector and dissipated over North India. Such wave disturbances play a crucial role in the energy distribution of the upper atmosphere and ionosphere. This research is the result of a collaborative effort among scientists from the Physical Research Laboratory, Ahmedabad; UCAR, USA; the Indian Center for Space Physics, Kolkata; the Airports Authority of India; and Krea University.
