6.6.2011: In collaboration with the Viennise company Veloce (www.veloce.at) the situmet team has started a field trail to investigate the integration of data from mobile sensors into the Ubimet weather analysis and forecast system.

In order to investigate the integration of real-time data from mobile sensors for the UBIMET weather analysis and forecast system, a field trail has been started on 06/06/2011 in the region of Vienna. For this reason, the situmet team equipped bike messengers from Veloce with 10 sensors (see figure 1) for their daily tours. Built for this purpose by the Freie Universität Berlin the sensors are attached to the bikers' backpacks (see figure 2) and measure temperature, air pressure and humidity every 30 seconds. The measured data is then sent via the mobile network to a broker developed by Fraunhofer ISST and for further analysis forwarded via internet to the UBIMET data server. The subsequent map provides an overview of the sensors' last locations within the last 24 hours (see figure 3). As a result UBIMET can make use of 10 extra weather sensors for their weather analysis that will help refining the sensor network and thus understanding e.g. the peculiarities of the Viennice climate.

Fig.3: The map provides an overview of the senors' current locations within the last 24 hours. Each red circles denotes one sensor. The sensor platform measures temperature, air pressure and humidity and sends the obtained data every 30 seconds to a broker. If the mouse pointer is positioned on the red circles the latest data available is show. As the time stamp is given in UTC one has to add to hours for CEST.
