Unfortunately it is already over! After four exciting days, the MTW Expo 2019 closed its doors on Friday, 07th June 2019. It was an exciting exhibition for us as we presented many innovations and had interesting conversations. A highlight this year was our new cloud-based application GRAWgo for the mobile monitoring of groundstations. Thus, GRAW Radiosondes marks the dawn of the new era of digitalization and recognized the signs of the times in the area of Industry 4.0. GRAWgo stores the meteorological data from weather stations in a cloud and provides historical data and real-time access to the status of weather stations and their radiosonde ascents, as well as measurement data, weather messages, diagrams and reports on the move. Another highlight was our new DFM-17 radiosonde, which attracted great interest from the weather services. Overall, we are very satisfied with the results of the MTW Expo and look forward to seeing you again in 2020.
