Acronym
CEPPAD
Full name
Comprehensive Energetic-Particle Pitch Angle Distribution
Purpose
To investigate quantitative information on the sources, energization, transport, and losses of energetic particles in the magnetosphere; and to measure the rate of particle precipitation into the Earth's upper atmosphere
Short description
