内容記述 | This paper describes a method for the retrieval of total precipitable water (W) in dry atmospheres, which relies on the strong water vapor absorption line at 183 GHz (for W less than 0.6 g/sq cm) and on the absorption near 90 GHz (for W above 0.6 g/sq cm). The method is very sensitive to the variations of W less than 0.5 g/sq cm and is complementary to the established methods that use the weak 22 GHz water vapor absorption line to retrieve W in the 1-6 g/sq cm. The technique was demonstrated by the analysis of two Advanced Microwave Moisture Sounder observations of dry atmospheres following cold-air outbreaks on March 13, 1983, and February 23, 1986. |
