TurboWin+ was made possible by E-SURFMAR and KNMI with contributions from several National Meteorological Services and endorsed by the WMO (World Meteorological Organization). Meteorological observations made on board ships are a substantial component of the World Weather Watch provided that the observation are accurate and of high quality. The VOS (Voluntary Observing Ships) are key components of the GOS (Global Observing System) and climate research. At the same time, however, it has been recognised that these observations are subject to keying errors, coding errors, calculating errors, etc.. To achieve an optimal control of the quality of the observations, before they are used in real time, the quality control has to be carried out at the root, by the observers themselves. TurboWin+ contains observation checking routines which are applied on the observations before they are transmitted. TurboWin+ is a user-friendly system with over 200 built-in quality checks. It allows the automated compilation of observations on board ships, their downloading to disk and their subsequent transmission ashore and thence to a Meteorological Centre, by using E-mail, REST API or other specific communication facilities. The program assists the observer with many menus, pictures, photos, forms, help pages, output options, automated calculations etc, TurboWin+ can also visualize the measured data of a linked automatic weather station or individual connected sensors
