DESCRIPTION:Speakers: Andrew Collier (Hermanus Magnetic Observatory)\nThe 
 principal source and loss mechanisms in the Earth's radiation belts are cu
 rrently not completely understood. Loss rates are important since they det
 ermine the duration of exposure of satellites to enhanced radiation condit
 ions during a geomagnetic storm. The dominant loss process is relativistic
  electron precipitation via resonant interactions with a variety of wave m
 odes. These interactions are governed by the characteristics of the plasma
 sphere. Current models provide an inadequate representation of the spatial
  and temporal evolution of the plasmasphere. In situ measurements of the p
 lasmasphere provide only local characteristics and are thus unable to yiel
 d a complete global picture. Ground based measurements\, based on the anal
 ysis of Very Low Frequency (VLF) whistlers and Field Line Resonances (FLRs
 )\, are able to describe large sections of the plasmasphere\, extending ov
 er significant radial distances and many hours of local time. These measur
 ements provide electron number and plasma mass densities.\n\nPLASMON is a 
 funded FP7 project between 11 international partners. PLASMON intends to a
 ssimilate near real time measurements of plasmaspheric densities into a dy
 namic plasmasphere model. The VLF whistler analyses will be conducted by a
 utomatic retrieval of equatorial electron densities using data from AWDAne
 t. Equatorial mass densities will be constructed from FLR measurements alo
 ng meridional magnetometer chains. The resulting model will facilitate the
  prediction of precipitation rates. The predicted rates will be compared t
 o observations from the AARDDVARK network.\n\nhttps://events.saip.org.za/e
