Analysis of the ionospheric equivalent slab thickness based on ground-based GPS/TEC and GPS/COSMIC RO measurements

摘要

In this study, the ionospheric equivalent slab thickness is derived from the Global Ionospheric Map (GIM) and the Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) ionospheric radio occultation (IRO) data. The spatial, diurnal, and temporal variations of the ionospheric equivalent slab thickness during the solar minimum phase (the year 2007) have been analyzed. The analytical results show diurnal and seasonal variations of the ionospheric equivalent slab thickness.
