Cloud Hosted Real-time Data Services for the Geosciences (CHORDS)

Cloud Hosted Real-time Data Services for the Geosciences (CHORDS) is a seed-funded project sponsored by the NSF EarthCube initiative (http://earthcube.org/). The goal is to lower the barrier for small research groups who want to provide Internet access to their real-time sensor data. 

The scientists follow a few simple steps to create a cloud-based web server and associated database, without the need for IT support and significant IT budgets. Sensor observations are submitted using HTTP queries. Similarly, the real-time data may be fetched as files, and brought into browser pages or analysis scripts, by the same method. The web server provides monitoring functions, so that the scientists can insure that their remote sensors are operating correctly. The research group has complete ownership and control of their own CHORDS Portal. 

Cost for the cloud computing is estimated to be $0.50/day on Amazon Web Services. Future versions of CHORDS will be possible to host on local systems, if that is desirable. There are currently four operational instances of CHORDS used by "friendly testers", providing real-time Internet access to a variety of data for systems in the U.S. and Italy.
