Short summary
In this paper we describe a novel way to approximate the decomposition of magnetospheric ultra low-frequency (ULF) wave power in key azimuthal wavenumbers m, which is a parameter describing the number of azimuthal wavelengths that fit within a particle drift orbit. This is a critical parameter that is required in estimates of the rates of radial diffusion, and we show for the first time that there is a local time and geomagnetic activity dependence in the distribution of power in wavenumbers m.
