In this work we study the Zeeman effect on stratospheric O2 using ground-based microwave radiometer measurements. The interaction of the Earth magnetic field with the oxygen dipole leads to a splitting of O2 energy states. which polarizes the emission spectra. A special campaign was carried out in order to measure this effect in the oxygen emission line centered at 53. https://www.mamapaisa.com/product-category/blow-dry-refresher/
