NCAR OpenIoTWx

This is the OpenIoTWx CHORDS Portal. OpenIoTWx is a low cost, modular, extensible, and pint sized 3D printed weather station based on Internet-of-Things (IoT) technology. Become part of our open source community to build, contribute, and deploy OpenIoTwx.

• Print: All parts can be 3D printed with most segments taking under 5 hours to complete on a standard 3D printer. Total print time of full station and base level accessories is 35 hours on an entry level printer.
• Configure: The station, its sensors, power source, and data transmission can all be configured to fit your needs, with a focus on low complexity to reduce time to data. No soldering. No breadboarding. No Electrical Engineering or Computer Science degree required.
• Deploy: OpenIoTwx can be deployed where you want (and have the permission to use). It can even be attached to mobile systems such as storm chasing vehicles, rovers, or boats. The possibilities are endless!

OpenIoTwx is Powered by Open Source, and follows the:

• Findable, Accessible, Interoperable and Reusable (FAIR)
and
• Collective benefit, Authority to control, Responsibility and Ethics (CARE)
Principles.

The platform is committed to community-maintained data sovereignty and control. We value collaboration, transparency, data sharing, and respect for privacy, while at the same time encouraging open, auditable, hackable, and solution-oriented systems.

Built on Open Architectures openIoTwx is built on Arduino, Micropython, and Linux, with a "click-and-play" approach to hardware. We encourage custom hardware sensor development, but also support Qwiic, Grove connectors supported by vendors such as Adafruit, Seeedstudio, Zio and Sparkfun. All code, designs, and data management tools such as CHORDS or Thingsboard are built on open architectures and protocols.

OpenIotWx is a product of the National Center for Atmospheric Research.

Detailed Information About CHORDS

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:

• To lower the barrier for disemminating real-time geoscience observations via the Internet.
• To provide a simple, "shrink-wrapped" and inexpensive service that will be especially attractive to teams that do not have IT expertise and budgets.
• To provide standards-based interoperability with next level processing systems.
