Abstract :

Earth�s magnetic field is highly dynamic and leads to several interesting processes in the magnetosphere. The energetic charged particles, gyrate, bounce and drift about these magnetic field lines, they can also get energized to relativistic energies through resonating with waves leading to pitch angle scattering and eventual loss into the atmosphere. The BARREL (Balloon Array for Radiation Belt Relativistic Electron Losses) mission was launched first in 2009 to study the electron losses in the atmosphere. Each balloon carries a NaI scintillator to measure the Bremsstrahlung X-rays produced by precipitating relativistic electrons as they collide with neutrals in Earth�s atmosphere, and a DC magnetometer. Here we discuss some findings from the mission and the role of wave particle interaction in the observations.
