Aufbau eines Wasserdampfradiometers und Messung von stratosphärischen Wasserdampfprofilen in den Tropen und in der Arktis
This work discusses the development and deployment of a ground-based 22 GHz water vapour radiometer at a new tropical research station in Venezuela. The data analysis comprises data collected with a similar instrument in Ny-Ålesund, Spitsbergen, and with the new instrument on the Zugspitze, Germany...
