SUMMARY:Sarah Glauert (British Antarctic Survey): 'Modelling the Earth’s 
 electron radiation belts'
TZID:Europe/London
UID:20190114-8a17841a65af78070165c8410f5e23bd@warwick.ac.uk
CREATED:20190108T134012Z
DESCRIPTION:Abstract: The high energy (> ~500 keV) electron flux in the E
 arth’s radiation belts is highly variable and has been observed to chang
 e by orders of magnitude within a few hours. As society is becoming incr
 easingly reliant on satellite technology it is important to understand\,
  and ultimately predict\, these changes as high energy electrons are res
 ponsible for potentially damaging internal charging in satellites. The i
 ncreasing use of medium Earth orbit (MEO) means that modelling the radia
 tion environment throughout the radiation belts is particularly relevant
 \, as there is relatively little long-term data available at MEO. The BA
 S Radiation Belt Model has been developed to model the drift-averaged\, 
 high-energy electron flux from the inner edge of the outer belt to the l
 ast closed drift-shell. I will describe the model and present some recen
 t results including the first very long-term simulation (30 years) showi
 ng the ‘climatology’ of the outer radiation belt and slot region\, an ex
 planation of the “impenetrable barrier” observed by Baker et al. (2014) 
 and the consequences of the slot region filling that can be seen during 
 active conditions. Additionally\, I will discuss how the model has been 
 adapted for use in forecasting.
