Abstract
Ozone is one of the important trace gases of the Earth's atmosphere. This study anal yses ground-based synergetic MW + IR method for remote measurements of ozone using ground-based instruments at Peterhof (SPbSU) - MW ozonometer and Bruker IFS-125HR Fourier transform infrared spectrometer. Numerical estimates of the errors and vertical resolution of remote measurements showed that uncertainties of remote ozone measurements at different altitudes vary from 5 to 20% or more. The vertical resolution of the MW + IR method varies from ~ 10 to ~ 12 km. These estimates demonstrate the potential for determining ozone in Peterhof using ground-based combined MW and IR measurements.
