Abstract
A highly sensitive receiver for the microwave ozone profiling instrument MOPI 5 has been developed. The receiver allows the simultaneous measurement of the pressure-broadened line shape of the thermally-excited rotational emission lines of middle atmospheric ozone and carbon monoxide at 110.836 GHz and 115.271 GHz, respectively. It exhibits a single side band noise temperature of 550-625 K. This paper describes the receiver design and compares the results of the first spectral line measurements obtained using two different digital fast Fourier transform spectrometer back-ends.
