Abstract :
The high resolution of the MAS (Millimeter wave Atmospheric Sounder from Space Shuttle) radiometer spectrometer (200 kHz) allowed for the first time a detailed comparison between measurements and model calculations of the Zeeman effect. Two one minute measurement samples taken during the NASA ATLAS-1 mission in March 1992 were compared with relevant model calculations and showed fairly good qualitative agreement. Thus for the first time the ZPM model calculations of the Zeeman effect of the upper atmosphere were verified as well as the existence of polarized thermal noise
