The response of the ionosphere over Ilorin to some geomagnetic storms

, 2014
The effects of some geomagnetic storms on the F2 layer peak parameters over Ilorin, Nigeria (Lat. 8:53 N, Long. 4.5 E, dip angle, 2.96 ) have been investigated.

Quiet-time variations of F2-layer parameters at Jicamarca and comparison with IRI-2001 during solar minimum

, 2008
We analyze Jicamarca ionograms to study the quiet-condition variations in the peak electron density (NmF2), its height (hmF2), and F2-layer thickness parameter (B0) of the equatorial F2 layer during solar minimum. The sunrise peak is found in hmF2 and B0

Improvement of SAMI2 with Comprehensive Photochemistry at Mid-Latitudes and a Preliminary Comparison with Ionosonde Data

Atmosphere
Photochemistry can significantly affect the ionospheric status. Adopting a comprehensive photochemical scheme with 60 reactions, primarily based on the recent systematic study of ion chemistry by Richards in 2011, we revised the open-source SAMI2 (Sami2 ...

The Empirical Canadian High Arctic Ionospheric Model (E‐CHAIM): N _m F ₂ and h _m F ₂

, 2017
We present here the Empirical Canadian High Arctic Ionospheric Model (E-CHAIM) quiet NmF2, perturbation NmF2, and quiet hmF2 models. These models provide peak ionospheric characteristics for a domain above 50°N geomagnetic latitude.
