This dataset provides diffusion coefficients of chorus waves, which are essential for understanding the scattering and transport of energetic particles in Earth's magnetosphere. The data were generated using the Full Diffusion Code (FDC) (Ni et al., 2008; Shprits and Ni, 2009; Orlova and Shprits, 2011), a widely employed tool in diffusion coefficient studies, and have been used in our research to model wave-particle interactions. By making this dataset available, we aim to support the broader scientific community in their investigations of magnetospheric dynamics and particle behavior.

The dataset includes diffusion coefficients for both upper and lower band chorus waves and is organized into three folders:
• UBC: Diffusion coefficients for the upper chorus frequency band.
• LBC_Low_till20: Diffusion coefficients for the lower chorus frequency band up to 20° latitude.
• LBC_Mid_20-45: Diffusion coefficients for the lower chorus frequency band between 20° and 45° latitude.
