Effective at the end of May 2018, Earth Networks will be changing the way we receive data from your personal weather station. We are discontinuing the Earth Networks PWS program but will continue to integrate your data via the NWS CWOP network. This change will make it easier for personal weather station owners to provide their data to Earth Networks, as well as services that utilize Earth Networks weather data.

CWOP stands for “Citizens Weather Observer Program”. It is a network of personal weather stations managed by the National Weather Service as a method of providing citizens a simple avenue for sharing their personal weather station data with both the National Weather Service and the world. There are over 800 organizations who utilize data from the NWS CWOP network. The NWS CWOP program is also known as the “APRS WXNET” program.

Earth Networks ingests date from NWS CWOP data through the NOAA MADIS service (data from NWS CWOP stations automatically flows into the NOAA MADIS service), which allows all NWS CWOP stations to automatically undergo a quality-control check to ensure quality weather station data on our network.

More information about the NWS CWOP program can be found by going to http://wxqa.com. Frequently asked questions about the NWS CWOP program are available at http://www.wxqa.com/faq.html. The steps to connect to NWS CWOP are also included below.

If you are already sending data from your personal weather station to NWS CWOP, you are already set in the transition, and data from your personal weather station will automatically flow into the Earth Networks weather station network. You will only need to disable “WeatherBug” publishing from your personal weather station publishing application to ensure your personal weather station is no longer transmitting data to the Earth Networks PWS system (which will be shut down at the end of May 2018).

Steps to connect your personal weather station to NWS CWOP:

1. Visit http://wxqa.com/SIGN-UP.html

2. Register for a NWS CWOP station ID by going to http://www.findu.com/citizenweather/cw_form.html. You will receive a station ID with two capital letters (the second letter will be “W”) and four numbers (for example CW4206).

3) You’ll also need to use a PWS publishing app or PWS publishing hardware appliance to send data to NWS CWOP. The PWS publishing app or PWS publishing hardware appliance you’ve been using to send data to the Backyard Network likely supports NWS CWOP. Here is a link to other publishing app and appliances:


4) Select the “CWOP”, “Citizens Weather Observer Program”, or “APRS WXNET” option in your PWS publishing app or PWS publishing hardware appliance

5) Enable publishing and enter in your NWS CWOP station ID.

6) Select the upload interval and you’ll be all set in sending your data to NWS CWOP.

Viewing your weather station on NWS CWOP to ensure your data is flowing into the NWS CWOP network is simple. Simply go to http://wx.findu.com/YOURNWSCWOPID. For illustrative purposes, here is a sample NWS CWOP station page for station ID CW4206:

http://wx.findu.com/CW4206 (sample url)

You’ll easily be able to see your station’s raw data, as well as graphs of your weather station’s data, plus a map of your weather station. If you live in the US, you’ll also see a radar image with your weather station’s location on the map.

Thank you for being a part of the Earth Networks PWS program and for ensuring that your data continues to flow to us through NWS CWOP. During the transition, you can continue to email pws@earthnetworks.com with any questions.
