Abstract

Ozone is one of the important trace gases of the Earth’s atmosphere. This study analyses ground-based synergetic MW + IR method for remote measurements of ozone using ground-based instruments at Peterhof (St.-Petersburg State University): MW ozonometer and Bruker IFS-125HR Infrared Fourier Transform Spectrometer. Numerical estimates of the errors and vertical resolution of the remote measurements showed that uncertainties of remote ozone measurements vary from 5 to 20% or more at different altitudes. The vertical resolution of the MW + IR method varies from ∼10 to ∼12 km. These estimates show the potential for monitoring ozone content in Peterhof combining ground-based MW and IR measurements.
