Stratospheric water vapour profiles, radiometer, microwave, tropics, arctic. - 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 during testing and finally in Venezuela. The new instrument is part of the Ḿ́érida Atmospheric Research Station ́́(MARS) in Mérida/Venezuela. The facility was constructed in close collaboration with the Universidad de los Andes in Mérida, the Forschungszentrum Karlsruhe and the Universität Bremen. The drivers for the project were the validation activities for the SCIAMACHY instrument on ENVISAT. The WARAM 2 is the first permanent water vapour radiometer in the tropics and is now installed permanently on the Pico Espejo near Mérida, test operation started in March 2004. Measurements from the three sites Mérida, Zugspitze and Ny-Ålesund are presented in this work and a characterisation of the new instrument will be given. The main focus of this work lays on the retrieval of stratospheric water vapour profiles from the measured spectra. It was possible to calculate the distribution of water vapour over an . @Bremen, Univ., Diss., 2004
