BackForward Variable: Solar magnetic field

Full name Solar magnetic field
Definition Vector magnetic field (1D or 3D) at the solar surface (photosphere/chromosphere)
Measuring Units Gauss Uncertainty Units Gauss
Horizontal Res Units arcsec Vertical Res Units
Stability Units % (Stability /decade)


Comment: Solar surface magnetic induction remotely inferred using optical/IR radiation. Generally measured in 3D (referred as vector magnetogram) or 1D (referred as line of sight magnetogram)
