From 28- to 30 June 2022 there was the first OpenSense Action Joint Meeting. OpenSense meeting was hosted by the Czech Technical University in Prague, Faculty of Civil Engineering (Thákurova 7, Prague 6).
During the Plenary Session Stakeholders and OpenSense members presented the last results and are currently running projects based on opportunistic sensors.
Discover the summary of all the presentations here: Plenary Session.
An example of the contribution proposed is the presentation of Baruch Kagan (Aeyecka, Israel): “Sensing of rainfall using opportunistic data from satellite communication terminals”.

■ ABOUT
Introduction to
OpenSense Action
Find out more about our COST Action (CA20136) OpenSense focused on Opportunistic Precipitation Ensing Network.
Despite advances in remote sensing, precipitation observations remain one of the weakest links in the description of Earth’s water cycle. This is especially critical in the face of climate change, human-induced hydrologic changes e.g. due to rapid urbanisation, and consequent increase in frequency and magnitude of extreme events.
Opportunistic sensing can greatly improve spatial and temporal resolution of standard precipitation monitoring networks on continental scale by complementing them with measurements from personal weather stations or devices primarily not intended for precipitation monitoring such as commercial microwave links or broadband satellite terminals.
The number of opportunistic sensors has already now exceeded traditional in-situ observations by an order of magnitude, and it is increasing exponentially. Nevertheless, it is still unclear how to make this data operationally accessible, achieve robust quality control of these observations, and integrate them into standard observation systems.
OPENSENSE brings together scientists investigating different opportunistic sensors, experts from national weather services, owners of sensor networks, and end-users of rainfall products to build a worldwide reference opportunistic sensing community.
It will i) overcome key barriers preventing data exchange and acceptance as hydrometeorological observations ii) define standards to allow for large-scale benchmarking of OS precipitation products developing new methods for precipitation retrieval iii) coordinate integration of the opportunistic observations into traditional monitoring networks, and iv) identify potential new sources of precipitation observations.
These coordinated activities will boost uptake of OS as precipitation observation methods and enable generation of high-quality precipitation products with unprecedented spatial and temporal resolution.
