Time variation of total electron content over Tucumán, Argentina [PDF]
Geofísica Internacional, 2004 The day-to-day variability of total electron content, TEC, at Tucumán (26.9S; 294.6E; Dip: -21.1) has been studied. The database includes TEC measurements by Faraday rotation during the high solar activity period from April 1982 (R12= 114) to March 1983 (

Localized total electron content enhancements in the Southern Hemisphere [PDF]
Annales Geophysicae, 2020 This paper is dedicated to the investigation of localized TEC (total electron content) enhancements (LTEs), which were detected in the Southern Hemisphere via the analysis of global ionospheric maps. Using data from different years (2014, 2015 and 2018),

The Tropical Total Electron Content Enhancement
, 2023 Abstract Continuous and regional measurements of total electron content (TEC) over the Americas have revealed that the most significant TEC values during the June solstice frequently reside over Central America. These TEC enhancements are observed during the June solstice afternoon hours, last for a few hours, are constrained to regions of ...

Electron density profile modeling
Annals of Geophysics, 1996 The Base Point Model (BPM) is used to model the electron density (N) profile in the ionosphere, This model assumes two Chapman profile expressions one for the bottomside and one for the topside, and requires a characteristic point called "F region base ...
