RAM‐SCB Runs on Request at CCMC

The Ring current–Atmosphere interactions Model (RAM) with Self‐Consistent magnetic (B) field (SCB) combines a large‐scale kinetic model of ring current plasma with a three‐dimensional (3‐D) force‐balanced model of the terrestrial magnetic field. RAM‐SCB simulates the evolution of major ion species (H+, O+, and He+ by default) and electrons as a function of azimuth, radial distance, energy, and pitch angle. Simulation outputs include the Dst index, and pressure and differential flux of the modeled species, thus providing benefit as a science code and to inform surface charging hazard within the model domain. Version 2.2 of this open‐source simulation code has now—as of 8 August 2023—been made available for Runs‐On‐Request via the Community Coordinated Modeling Center. Plain Language Summary RAM‐SCB is a unique simulation code that models the evolution of major ion species and electrons in geospace, while also capturing their effect on the Earth's magnetic field. The simulations describe the evolution of geomagnetic activity levels and the environment that can cause harmful electrical discharge on satellites. As of 8 August 2023, this model is available to the community through the Community Coordinated Modeling Center Runs‐On‐Request service. Key Points The Ring current‐Atmosphere interactions Model (RAM) with Self‐Consistent B field (SCB) is now available for runs‐on‐request via Community Coordinated Modeling Center The deployed configuration of RAM‐SCB version 2.2 provides fast, robust inner magnetosphere simulation capability RAM‐SCB model outputs include the Dst index and differential ion & electron fluxes
