Abstract: A quasi-operational process for the determination of water vapor fields from METEPSAT-1 water vapor channel data is described. Each count of the WV picture is replaced by the corresponding mean relative humidity value using ...

Abstract: A new kind of frost-point hygrometer has been developed for horizontal soundings of the lower stratosphere. The cooling source, using the radiative cooling of a blackbody during the night, is able to cool the mirror down ...

Abstract: An electrified wire suspended in a supercooled cloud generates a jet of ice crystals only when there is ice on the wire. On a clean platinum wire no ice forms an the wire down to ?20C, but if the wire is coated with a ...

Abstract: In this paper, quantitative studies of water vapor Meteosat imagery, based on an accurate transmittance and radiance model are described. Using conventional radiosonde data, a linear relation between cloudless radiances ...
