First results from ground-based daytime optical investigation of the development of the equatorial ionization anomaly [PDF]
Annales Geophysicae, 1996 A meridional scanning OI 630.0-nm dayglow photometer was operated from Ahmedabad (17.2°N dip lat.) scanning a region towards the south in the upper atmosphere extending over ~5° in latitude from 10.2°N to 15.2°N dip latitude.

Motions of the equatorial ionization anomaly crests imaged by FORMOSAT‐3/COSMIC
Geophysical Research Letters, 2007 The equatorial ionization anomaly (EIA) structures and evolutions are imaged using radio occultation observation of the newly launched FORMOSAT‐3/COSMIC (F3/C) satellite constellation. Three‐dimensional ionospheric images provide unprecedented detail of the EIA structure globally. This paper presents images of the EIA structures during July–August 2006

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

High resolution 2-D maps of OI 630.0 nm thermospheric dayglow from equatorial latitudes [PDF]
Annales Geophysicae, 1998 The first-ever high resolution 2-D maps of OI 630.0 nm dayglow obtained from equatorial latitudes clearly reveal the movement as a large-scale feature of the equatorial ionization anomaly (EIA).

Ionospheric irregularities: The role of the equatorial ionization anomaly [PDF]
Radio Science, 1997 The availability of similar ionosondes at four locations in India covering the regions from the equator to the northern crest of the equatorial ionization anomaly (EIA) has provided a unique opportunity to study the role of the EIA and related processes in the occurrence of spread F.

Impact of sudden stratospheric warmings on equatorial ionization anomaly [PDF]
Journal of Geophysical Research: Space Physics, 2010 We investigate the ionospheric response to several stratospheric sudden warming events which occurred in Northern Hemisphere winters of 2008 and 2009 during solar minimum conditions. We use GPS total electron content data in a broad latitudinal region at ±40° geographic latitude and a single longitude, 75°W.
