The OpenSense short online conference should bring the OpenSense community the idea of the newest opportunistic sensor data achievements concerning opening data, data processing algorithms, and applications. The first conference will take place on 28 November 2023, at 9:00 CET.
Alexander Kann will present on CML data assimilation for precipitation forecasts over Austria.
Due to its sensitivity to the atmosphere’s moisture content, commercial microwave link data from mobile phone operators provide a valuable complementing data source to the conventional meteorological observation network. For precipitation analysis and forecasting, state-of-the-art models usually rely on rain radar and in-situ measurements from hydro-meteorological station networks. However, especially in Alpine regions, the observations have deficiencies, e.g. due to radar blocking effects or due to other local effects which are not represented well enough by the networks. The presentation will give a brief introduction to the CML data over Austria and its conversion to rain rates. The NWP model (AROME) and the analysis and nowcasting system (INCA) will be introduced, along with the assimilation procedure of the CML data. Finally, the impact of the CML data on the model performances will be discussed, ending with an outlook on further activities and recommendations towards improved applications.
Erlend Øydvin will present on Combining commercial microwave links and weather radar for rain and dry snow detection.
Our study explores the synergy between Commercial microwave links (CMLs) and weather radar data to classify precipitation types. While CMLs estimate rainfall through signal loss, dry snow causes little signal dampening and appears as dry events. Addressing the limitations of weather radar in distinguishing precipitation types, we propose to combine weather radar wet events with CML dry events to accurately classify dry snow events. The estimates are compared with nearby disdrometer ground truth data across multiple locations in Norway.

Short online conferences (max. 1 hour; every two months) should bring the OpenSense community the idea of the newest opportunistic sensor data achievements concerning opening data, data processing algorithms, and applications. During the conference, two speakers will be invited (20 min talk + 10 min discussion).
