The University of Hertfordshire (Prof. Joseph Ulanowski) has commissioned enviscope GmbH to deliver the “Cloud and aerosol dropsonde system for FAAM aircraft” which is based on the formerly developed “KITSonde” system. This system will initially be installed on the British BAe-146 research aircraft. It is intended to acquire data of meteorological dropsondes, as well as the data from the “Universal Cloud and Aerosol Sonde System (UCASS) “.
