ULF Wave Radial Diffusion Coefficients

<p>Hourly radial diffusion coefficients, DLL, derived from ground-based magnetometer measurements from March 16 to March 20, 2015 in units of days^-1.&nbsp;The DLL values are plotted out at 100 equally spaced L* values from L*=1 to L*=5 derived from the TS05 magnetic field model at K=0&nbsp;G^1/2Re.&nbsp;These DLL values are used to reproduce the the evolution of the electron phase space density profiles in the Earth&#39;s outer radiation belt during the March 2015 geomagnetic storm&nbsp;presented in:</p> <p>Ozeke et al.,&nbsp;The March 2015 Superstorm Revisited: Phase Space Density Profiles and Fast ULF Wave Diffusive Transport, Journal of Geophysical Research, 2019, submitted.</p> <p>The attached plot shows a comparison of these event specific diffusion coefficient with those obtained from the empirical models of:</p> <p>Brautigam,&nbsp;D.
