Internal charging refers to the accumulation of electric charge on interior, ungrounded metals or in the dielectrics inside a spacecraft by penetrating/energetic electrons. The resulting discharge is termed as IESD (Internal ElectroStatic Discharge). Electrons greater than 100 keV are responsible for internal charging (the main source is radiation belt electrons). 


1. Finding internal charging events
2. Model performance assessment and improvement 
3. space environment model scoreboard that is relevant to internal charging

Expected output

  1. More systematic assessment of model performance under different conditions
  2. Better near realtime monitoring and/or forecasting capabilities of internal charging environment
