Modeling the Development of Plasmasphere Ducts and Irregularities With SAMI3/WACCM-X

We find the equatorial electron density is irregular as a function of longitude which is consistent with CRRES measurements (Clilverd et al., 2007, ). We also find that plasma ducts can be generated for L-shells in the range 1.5-3.0 with lifetimes of similar to 0.5 hr; this is in line with observations of ducted VLF wave propagation with lifetimes of 0.5-2.0 hr (Clilverd et al., 2008, ; Singh et al., 1998, ).
