Abstract : The authors present new 6.0 and 21.1 cm interferometric observations of Venus. When combined with our previous 3.12 cm work they provide a self-consistent set of high-resolution observations at three wavelengths covering a range in which the opacity of the Venus atmosphere varies by a factor of fifty. Model calculations indicate that a model atmosphere of CO2 in adiabatic equilibrium containing uniformly mixed gaseous absorbers surrounding a dielectric sphere cannot simultaneously and adequately predict the radio interferometric measurements at all wavelengths together with the radar and radio occulation measurements.
