Weather Observations in Dallas-Fort Worth Network

Colorado State University

The Dallas-Fort Worth urban metroplex serves as a testbed for a variety of atmospheric sensing instruments and networks. The region is prone to convective storms, flash floods, tornadoes, as well as ice storms, stratiform precipitation, drought, and wildfire. The damage associated with these extreme phenomena can be quantified in the millions of dollars and thousands of lives. As such, the area is home to experimental nowcasting networks such as the CASA radar network, and the Understory weather station and hail sensor system, as well as NEXRAD and various other networks. As such, it is imperative to employ a system capable of integrating these disparate sources of data, distilling the information to actionable items and crucial data points. To that end, this CHORDS Portal has been developed to serve the real-time data needs of this complex region of study.

CHORDS
Cloud-Hosted Realtime
Data Services
for the Geosciences

CHORDS is supported by the National Science Foundation EarthCube initiative, which is a community-led cyberinfrastructure initiative for the geosciences.

You are looking at a CHORDS Portal. This is a web service that allows scientists to easily provide Internet access to real-time streaming data. Typically these data are measurements made by diverse instruments, which are deployed in support of a particular research effort.

Each research team can operate their own portal, which is created simply by running a copy of the CHORDS appliance on Amazon cloud services. This provides a web server and database. CHORDS can both ingest and deliver data via simple http: requests, just like any web browser. Configuration and management of your private CHORDS server is also done through a web interface. Any user on the Internet can attach to the data streams using tools of their choice, such as Matlab, Excel, Python, web browsers; i.e. anything that is able to issue an http: request.

CHORDS portals can also forward real-time data streams to higher level CHORDS services, which might provide functions such as OGC compliant formatting, mapping services, federation, and just about anything else you can think of.

The goals of CHORDS are:
