* APRS Protocol:  CWOP uses the APRS protocol to format its messages.  Here's a couple places to learn more about APRS formatted weather messages:
        -  Philip Gladstones APRSWXNET Page (learn by example):   http://pond1.gladstonefamily.net:8080/aprswxnet.html
        -  Raw data stream example:  http://www.findu.com/cgi-bin/rawwx.cgi?call=CW0351
        -  TAPR Full APRS© Specification (pdf file):   ftp://ftp.tapr.org/aprssig/aprsspec/spec/aprs101/APRS101.pdf

  1. CWOP data are sent in real-time from your Personal Weather Station (PWS) via the Internet or through a Ham Radio wireless RF broadcast to a site with an Internet connection (Digipeater)
  2. Data are forwarded to the CWOP servers, using the round-robin domain "cwop.aprs.net" port 14580.  
  3. Data are sent to the FINDU server where html time series web pages are created for CWOP members and files are queued for pickup by the NOAA Global Systems Division.
  4. Finally, NOAA Global Systems Division fetches the data from FINDU every 15 minutes and ingest the data into the Meteorological Assimilation Data Ingest System (MADIS) database (as "APRSWXNET" data type) where data are quality controlled, merged with over 25,000 other surface observations and forwarded to other NOAA workcenters, including some Weather Forecast Offices (WFO)... more info about MADIS.

CWOP servers supporting CWOP connections:  APRS nodes and ports (blue columns below) are used in data logging software to send data to CWOP/APRSWXNET

SYSOP/Email Web Page Server Status APRS Node  Port
Gerry Creager http://cwop.aprs.net:14501/ Note:  "cwop" is not an actual server, pseudo 'round-robin' load sharing.  We recommend "cwop.aprs.net" be your primary server. cwop.aprs.net 14580

Notes: 

  • Software connecting to CWOP/APRSWXNET should only use the cwop.aprs.net server, port 14580 as the primary server and automatically "roll-over" to servers listed above if the primary server is unreachable.
  • Suggest CWOP/APRSWXNET members send their data every 15 minutes, optimally every 10 minutes (but not more frequently than every 10 minutes as this could stress server bandwidth)
  • If your data logging applications does not have auto-rollover (those programs other than VWSAPRS and WeatherDisplay) and should a server stop accepting your weather messages, you will have to manually reconfigure your CWOP setup to point to an alternative APRS-IS server (see APRS Nodes and ports in blue shaded columns in above table).  Check the cwop.net "News" page to verify that it is the server and not your Internet connection or computer problem.

Notes:
-- Data displayed with over 18,000 surface observations
-- Must first register with valid latitude/longitude and successfully send data through FINDU/APRS before appearing on MADIS
-- Will take about 1 week to get the new "CW"s onto NOAA MADIS (after confirmation with Russ); database updated every Wednesday afternoon (~23:00GMT)

*  NOAA's MADIS Quality Control and Monitoring System (QCMS) was developed to assist NWS meteorologists use mesonet data on their AWIPS workstations.  QCMS uses automated validity, internal consistency, temporal, and spatial checks to evaluate data quality (read more about QCMS).  Your station's performance statistics are available at these locations:        
- NOAA's QCMS Statistics for APRS Wx Net Citizen Weather ("flagged" stations only)  HourlyDaily   |  WeeklyMonthly
- Russ Chadwick's QCMS Interactive Retrieval Page
- Get feedback of your weather station's performance by registering with Phillip Gladstone Quality Reporter Suite which includes a Quality Assurance Listserver and Graphs Email Service (strongly recommended for CWOP members):   
        o Sign up for daily weather station QCMS performance statistics to be emailed to you:

        o Participate in a discussion of weather station operations list server:

CWOP and Internet SecurityParticipating in the CWOP does not by itself increase risk from Internet attacks.  CWOP communications protocol does not allow other computers to connect to your computer, rather CWOP members connect to a trusted CWOP server, upload your weather data, and immediately disconnect.  No data is sent from the CWOP server to your computer. 

However, increased exposure to the risks of computer software damage, denial of service, and identity theft is possible if you don't take steps to educate and protect yourself when using the Internet.  We have created the "CWOP and Internet Security" page to help CWOP members improve their computer security. 

While you should patch computer insecurities using software and hardware, you also must resist responding to emails requesting personal information.  This fraudulent activity by criminals is called "phishing." Read more about phishing in this article from the Washington Post.  Beware of identity theft!
