Description: 

Monitoring of volcanoes in real-time has increased over the past decade as data transmission and cyberinfrastructure capabilities evolve. Since 2016, the multinational GNSS network TZVOLCANO was initiated to (1) improve our understanding of volcano-tectonic interactions during continental rift initiation at a range of temporal scales and (2) provide volcano deformation monitoring capabilities for local constituents. The TZVOLCANO network consists of 6 continuous GNSS stations with 3 streaming 1 second ~4 cm precision positions and 1 co-located compact broadband seismometer. Here, we describe our implementation of the EarthCube cyberinfrastructure CHORDS (Cloud-HOsted Real-time Data Services for the Geosciences) that we use to evaluate real-time streaming positioning data available through UNAVCO Real-Time GPS/GNSS Data Services, send email alerts for vertical velocities exceeding thresholds, and provide information about GNSS station health. In conclusion, we describe a Python-based brokering code that connects UNAVCO Real-Time GPS/GNSS Data Services with CHORDS such that additional users of real-time GNSS data can easily stream data into a CHORDS portal and build their own additional capabilities via its simplified interface.
