Imaging of the equatorial ionosphere
atmosphere electromagnetic methods remote sensing tomography data processing GPS TEC
2015/9/10
The equatorial anomaly is the dominant structure in free electron concentration in the tropical ionosphere. Due
to its edges (crests) which are characterised by steep latitudinal gradients in TEC and...
Evaluation of soil thermal diffusivity algorithms at two equatorial sites in West Africa
Thermal diffusivity Soil temperature Soil moisture content West Africa

This study presents comparisons between six algorithms used in the calculation of apparent thermal diffusivity (Kh) of the topsoil during measurement campaigns conducted at two equatorial sites. It fu...
Nonlinear features of equatorial baroclinic Rossby waves detected in Topex altimeter observations
Nonlinear features equatorial baroclinic Rossby waves Topex altimeter observations
2009/11/16
Using a recently proposed technique for statistical analysis of non-gridded satellite altimeter data, regime of long equatorially-trapped baroclinic Rossby waves is studied. One-dimensional spatial an...

Ionospheric two-stream waves and gradient-drift waves nonlinearly
drive a large-scale (D.C.) current in the E-region ionosphere. This current flows
parallel to, and with a comparable magnitude to, t...
