Electromagnetic ion cyclotron electron diffusion coefficients calculated using Van Allen Probe EMFISIS data for a range of ion compositions
The banded structure of Electromagnetic Ion Cyclotron (EMIC) wave spectra and their resonant interactions with radiation belt electrons depend on the cold ion composition. However, there is a great deal of uncertainty in the composition in the inner magnetosphere due to difficulties in direct flux measurements. Here we determine the sensitivity of electron diffusion by EMIC waves to the cold ion composition. The diffusion coefficients are calculated using collocated EMIC waves spectra and plasma densities observed by Van Allen Probe Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) data, parameterised by Dst, using quasi-linear theory implemented in the Pitch-Angle Diffusion of Ions and Electrons (PADIE) code.

Methodology:
Data sources:
* OMNIWeb ( https://omniweb.gsfc.nasa.gov) for the geomagnetic and solar wind indices.
* Van Allen Probes data the Level 3 and Level 4 EMFISIS magnetometer data obtained from http://emfisis.physics.uiowa.edu/data/index.
The wave data was processed in Ross et al. (2021) and the technique for calculating the diffusion coefficients is given in that paper.
Data collection:
