The ozone lines at 273.051 GHz and 274.478 GHz are the strongest in the frequency range covered by the
radiometer. Due to the good signal to noise ratio of the measured spectra a high resolution in the
profiles has been achieved.
The 273.051 GHz ozone line, measured on March 29 (left) and the 274.478 GHz line, measured on February
19 (right).
The red spectra are corrected for standing waves.
