| مستخلص: |
Atmospherics or sferics originating from lightning discharges on propagating large distances in the Earth-ionosphere waveguide, particularly at the night, form dispersed sferics called tweeks. Tweeks have been successfully used as novel diagnostic tool to probe the nighttime D-region ionosphere. From the analysis of tweeks the path integrated mean ionospheric reflection height and path integrated mean electron density can be estimated. Some of the results on D-region parameters estimated using the higher harmonic tweeks recorded in the time between 21-03 hrs LT at Suva (18.2° S, 178.3° E), Fiji, during March 2006, are presented.
