Polar Data Centre, Natural Environment Research Council, UK. https://doi.org/10.5285/7d2cc962-d4cf-4ce6-b3ae-96bc825c977a This data set contains the ULF wave model output data required to produce the figures in the article: A. W. Degeling, I. J. Rae, C. E. J. Watt, Q. Q. Shi, R. Rankin and Q. G. Zong, "Control of ULF Wave Accessibility to the Inner Magnetosphere by the Convection of Plasma Density", J. Geophys. Res. (accepted Dec. 2017) doi:10.1002/2017JA024874 The dataset has a Matlab binary file format. It consists of a structure array "d" (with 325 elements). These elements correspond to the 2D parameter scan in driver frequency and elapsed time during plume development performed for this study. The elapsed time parameter has 25 elements, ranging 0 to 24 hours (i.e. 1 hour spacing), and the driver frequency parameter has 13 elements ranging from 1 to 7 mHz (with 0.5 mHz spacing). e.g. use "d = reshape(d,25,13);" to reshape the structure array into 2D with columns for the frequency scan and rows for the elapsed time scan. The Matlab function "make_PDP_figs.m" is used to read the data, perform the necessary post-processing operations and output the article figures. To produce all six figures, simply run the file without any input arguments.

L2: [2121x20 double]: Shear Alfven Wave eigenvalues calculated on the coarse mesh. ips: [1x1 struct]: Model input parameters - contact A. W. Degeling for more information. rho: [2121x1 double]: equatorial plasma mass density, defined on the coarse mesh. u: [342040x1 double]: ULF wave electric field raw output data, defined on the refined mesh. This data consists of the complex amplitudes of cartesian components (in the equatorial plane) for 10 spectral method basis functions (in the field-aligned direction) which are used to define the wave electric field on the equatorial mesh. The equatorial electric field components Ex and Ey are given by simply summing over these 10 amplitudes. For example, Ex and Ey (in mV/m) are obtained by the following Matlab code: N = 10; nn = 1:N; no_ps = length(pn(1,:)); mVpm = ips.const.mVpm; uu = reshape(u,no_ps,2.*N); Ex = sum(uu(:,2.*nn-1),2).*mVpm; Ey = sum(uu(:,2.*nn),2).*mVpm; The Matlab function "make_PDP_figs.m" is used to read the data, perform the necessary post-processing operations and output the article figures. To produce all six figures, simply run the file without any input arguments. asNeeded completed
