Electron Electromagnetic Ion Cyclotron diffusion coefficients calculated from Van Allen Probe observations
Electromagnetic Ion Cyclotron (EMIC) wave are important for the losses of ultra-relativistic electrons from the Earth's radiation belts. In this work, statistical EMIC diffusion coefficients are calculated from Van Allen Probe A observations of EMIC waves from the entire mission. The diffusion coefficient calculations include the observed L* and activity dependent distributions in plasma density and wave spectra so that the wave-particle interactions modelled are representative of those in the radiation belts. These diffusion coefficients can be included into global radiation belt simulations such as the BAS radiation belt model. The study is published in Ross et al 2021, JGR: Space Physics.

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.
Data collection:
Code: BAS-RBM (Glauert, S. A., Horne, R. B., and Meredith, N. P. (2014), Three-dimensional electron radiation belt simulations using the BAS Radiation Belt Model with new diffusion models for chorus, plasmaspheric hiss, and lightning-generated whistlers, J. Geophys. Res. Space Physics, 119, 268- 289, doi:10.1002/2013JA019281.)
Code: PADIE (Glauert, S. A., and Horne, R. B. (2005), Calculation of pitch angle and energy diffusion coefficients with the PADIE code, J. Geophys. Res., 110, A04206, doi:10.1029/2004JA010851.)
Data quality:
The magnetometer data using in the study are converted in to spectra following the procedure described in the accompanying paper. EMIC waves were identified in the resulting spectra using a visual identification and machine learning, the method excluded features that cannot reliably be identified as EMIC waves.
