Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAShas co-authored an article titled ‘Resolving the generation mechanisms and electrodynamical effects of Medium Scale Traveling Ionospheric Disturbances (MSTIDs)’ which has been published in Frontiers in Astronomy and Space Sciences. The work is a perspective article resulting from detailed deliberations of an international team of researchers for 2-3 years led by a NASA scientist. The team has gathered twice at Bern to discuss outstanding problems regarding an ionospheric phenomenon called Medium Scale Traveling Ionospheric Disturbances (MSTIDs). MSTIDs are perturbations propagating in the ionosphere of earth, and they are caused by different mechanisms that are not well understood/characterized. MSTIDs affect satellite based communication, navigation and radio astronomical observations. In this article, they discuss the most important issues in their characterisation and point to some of the inconsistencies that exist in the literature. They also provide some recommendations to the community to address these issues.
