Comparison of Total Electron Content with International Reference Ionosphere Model Predictions near the Northern Crest of EIA at Bangladesh

Total electron content (TEC) observations extracted from a Global Positioning System (GPS) receiver station in Dhaka, Bangladesh (geographic latitude $23.8^{\circ}N$, longitude $90.4^{\circ}E$, geomagnetic latitude $14^{\circ}N$) under the northern crest of equatorial ionospheric anomaly (EIA) is investigated. Eight years of TEC measurements from 2004-2011 constitutes an extensive dataset, which p...
