Advanced Composition Explorer (ACE) Magnetic Field Experiment (MAG) Level 2 Data
Listed in NASA Earthdata CMR
The Magnetic Field Experiment (MAG) consists of twin vector fluxgate magnetometers controlled by a common CPU.
Description
The sensors are mounted on booms extending 4.19 meters from the center of the spacecraft at opposite sides along the +/-Y axes of the spacecraft. The instrument returns 6 magnetic field vector measurements each second, divided between the two sensors, with onboard snapshot and FFT buffers to enhance the high-frequency resolution.
MAG level 2 data is organized into 27 day time periods (Bartels Rotations - roughly one solar rotation period). For each Bartels Rotation, the level 2 data contains time averages of the magnetic field data over the following time periods: - 16 seconds - 4 minutes - hourly - daily - 27 days (1 Bartels rotation) See: srl.caltech.edu/ACE/ASC/level2/mag_l2desc.html
