Full name
Interplanetary magnetic field
Definition
Vector magnetic field (3D) in the solar wind. The reference frame is Cartesian or Cylindrical with many different axis orientations. Important in Space Weather to monitor magnetic disturbances of the near earth environment.
Measuring Units
nanoTesla (nT)
Uncertainty Units
nanoTesla (nT)

Stability Units
nanoTesla (nT) (Stability /decade)
Comment:
Variable typically measured in situ at the L1 Lagrange point, but also valuable at other locations such as the L5 Lagrange point. Vital for forecasts and warnings of geomagnetic storms.
