Laboratory measurements of the microwave (1.2-22.3 cm) spectrum properties of Venus' gaseous atmospheric constituents were performed using an apparatus for simulating conditions of the middle atmosphere of Venus (gaseous H/sub 2/SO/sub 4/ + CO/sub 2/ at 1 to 6 atm). The results have shown that at wavelengths longer than 1.8 cm, gaseous H/sub 2/SO/sub 4/ and CO/sub 2/ are the predominant microwave absorbers, while at wavelengths from 1.2 to 1.8 cm, SO/sub 2/ and CO/sub 2/ are the predominant absorbers. These results were used to develop a model for the microwave emission spectrum of Venus, which correlated well with microwave observations of this planet. 24 references.
