Remote measurement of planetary magnetic fields by the Hanle effectResonance fluorescence lines in the spectra of planetary atmospheres are polarized. They will be depolarized by magnetic fields in the scattering medium (Hanle effect). The amount of depolarization was calculated for some atomic (FeI, CaI) lines and some molecular lines (NO gamma bands) seen in the Earth's day glow spectra. The results are presented and the potential advantages of LIDAR measurements for obtaining atmospheric magnetic fields are discussed. The depolarization of Na and Ca lines are suitable for measuring magnetic fields in and near Io.
