ISSI Bern > International Teams > Precipitation of Energetic Particles from…

First meeting

First meeting was held from September 30 to October 4, 2024.

We have discussed three scientific questions.

Q1: What is the missing loss mechanism of ring current electrons besides the diffusive scattering by whistler-mode waves?

Q2: What is the energy of electrons that are significantly influenced by EMIC waves? A related question is why is the EMIC wave activity in the magnetosphere not always accompanied by the energetic particle precipitation at the conjugate point on LEO orbit?

Q3: Which energy range of precipitating electrons has the largest impact on the chemistry and dynamics of the middle atmosphere?
