Abstract: Superpressure balloons are used as radiometers to perform in-situ radiometric determinations in the lower stratosphere. The method consists in measuring the temperature of both the lifting gas and the ambient air and then ...

Abstract: The database obtained by Rayleigh lidars over the south of France is now used for monitoring the middle-atmosphere structure and to validate satellite data. For these reasons it is crucial to ensure the quality of the data. ...

Abstract: Systematic cirrus lidar measurements performed in the south of France during 2000 are analyzed statistically to search for cloud classes. The classes are based on cloud characteristics (cloud thickness, light backscattering ...

Abstract: The 2002 Antarctic winter was characterized by unusually strong wave activity. The frequency and intensity of the anomalies increased in August and early September with a series of minor stratospheric warmings and culminated ...

Abstract: Daily NMC analyses, constructed from operational TOVS data since 1978, are used to monitor behavior of middle atmospheric temperature. Capability of the upper-stratospheric analyses (5, 2, 1, and 0.4 mb) to provide temporally ...
