Sep 10, 2015 - Fifteen years ago today, Sept 10, 2000, the CWOP member database was started, entries from a few interested hams were entered, and data started flowing. We (Steve Dimse and I) expected maybe a hundred people or so would join and send data to Steve's findu.com server for transfer to NOAA. So far, well over 30,000 have joined and over 12,000 stations are currently sending data, about 100,000 packets per hour. CWOP is the largest network in the MADIS surface data set, both in terms of members and observations. It has all turned out better than we thought it would.

Mar 28, 2013 - Davis Weather Products has issued firmware update 3.12 for Vantage Pro2, Weather Envoy, and Firmware 3.14 for Envoy 8X stations that were manufactured after April 2006. If you have a console manufactured before April 2006, you should stay with Firmware 1.90. (Note: If you try to install firmware version 3.12 on a Vantage Pro2 or Weather Envoy and the unit does not display inside temperature, inside humidity or barometric pressure readings, it means that you have a unit that was manufactured before April 2006. To correct this, simply download and reinstall firmware Version 1.90.) These updates may be downloaded from the Davis website.
Jan 09, 2013 - Jon Racy, long-time CWOP member CW0752, passed away on Jan 08, 2013. Jon was the Lead Forecaster at Storm Prediction Center (SPC), in Norman, OK.

Oct 09, 2012 - The CWOP1 server recently relocated from Texas A&M to the University of Oklahoma, as discussed in the Sep 30 item below, is now up and running. CWOP server availability can be checked here. Any CWOP member using a CW.... DW.... or EW.... ID should be sending packets to one of the CWOP servers or to cwop.aprs.net. The latter is a round robin that will be more reliable. Folks using CW.... DW.... or EW.... IDs should not be sending packets to ham radio servers even if they have an APRS validation code. More information on which servers to use is here.
Oct 02, 2012 - The uptime history of the WXQA.COM web site goes back to July 2009.
Sep 30, 2012 - Davis Weatherlink update 6.0.2, mentioned Sep 17 below, has re-appeared on the Davis website. No reports from anyone who has used it. So, test carefully before use.
Sep 20, 2012 - For many years, CWOP and APRS servers operated at Texas A&M and supplied reliable and valuable service to the CWOP community. Those servers were deactivated at 1800z on Sept 12 because Gerry Creager (AP009), who kept them going, moved to a new position at the University of Oklahoma. Gerry hopes to be able to provide the same service to the CWOP community from a new location in the near future. In addition to operating CWOP1, CWOP4, CWOP Aggregator and findU backup, Gerry also operated first.aprs.net and firenet.us. When either of these links becomes active, the CWOP1 server will follow close behind. CWOP1 availability can also be checked here.
Sep 17, 2012 - In response to a question by Ron Pippin (CW5020) about why software update 6.0.1 (Aug 21 item below) was no longer available on their web site, Davis tech support replied "There was a problem with 6.0.1 having to do with the annual network subscription. If you are not using that than you should be fine." Update version 6.0.2 will be available on the Davis web site soon.
Aug 21, 2012 - Davis Weather has just posted an update to the Weatherlink Program for Windows. The update (6.0.1) allows the software to rotate through the available CWOP/APRS servers until CWOP upload is successful. This fixed a bug, which on some systems, reduced reliability when changing servers. The update may be downloaded here.
Aug 2, 2012 - Jim Dudley and Marc Ganey have revised and updated their APRS Setup Guide on how to build and set up an AC or DC solar-powered APRS Weather Station based on their experience setting up several CWOP weather stations in the remote mountains near Hanford, CA. Additionally, Marc created a you tube video showing the steps to setting up a Solar Powered Davis APRS unit as has been done at several locations.
May 23, 2012 - The compressed raw data packets containing solar radiation measurements collected at APRS and CWOP stations for the past four years are now available through the Solar Data Page near the bottom.
Apr 26, 2012 - If you have updated the software for both WeatherLink and the Vantage Pro2 and find that the packets to CWOP have zeros as barometer data, look for Vantage Pro2 firmware version 2.03. Erich DW8823 reports that it fixed the problem for him. Apparently, the problem does not occur with a wireless system.
Apr 24, 2012 - Ron CW5020 reports that Davis Instruments has updated its Weatherlink software. Version 6.0.0 is available from the Davis website for current owners of its software.

Entering ? for Call Sign and a recent date here will return a list of stations available.
Jan 31, 2012 - On Jan 28, during extremely cold weather in Alaska, a temperature of -79F was reported by CWOP station JMTA2. The weather instrument at this site is a Davis Vantage Pro 2 and is not rated to report accurately at temperatures colder than -40F. Also, it has been noted that when the ambient air temperature drops colder than -50F, the wireless Davis Vantage Pro 2 weather stations experience a significant drop in battery voltage. This drop in battery voltage results in a dramatic and unrealistic drop in the temperature observed by the temperature sensor. Here is a NWS Public Information Statement regarding the low temperature report at JMTA2 (Jim River DOT). Note that the manufacturer makes no claim that the station is accurate below -40F. Prior to the event, MADIS quality checking reported "...sensor is reading COLDER than expected".
Jan 09, 2012 - Price of Thermometer Soup is determined by yesterday's temperature. Details are here. Sounds like a good deal for a cold winter day (or the next day after a cold winter day:)

Dec 06, 2011 - Since the tsunami and resulting nuclear accident in March, Japanese amateur radio operators have deployed radiation measurement devices and are sending the measurements through APRS. The locations are shown here after you zoom out six steps. Individual measurements can be seen by looking at the raw data for the individual stations and noting the three numbers after "X" in the data field. Details of the APRS radiation data format are in the March 25, 2011 CWOP News item below.
Nov 22, 2011 - Mike Hardiman of the NWS El Paso WFO (Weather Forecast Office) recently asked the New Mexico Department of Public Safety if they could add their small network of Davis Weatherlink stations to CWOP, and they graciously did so. These stations are mostly located at "Port of Entry" weigh stations and rest areas (zoom out to see them all). The only station not currently reporting is DW8893, as it is essentially in the middle of nowhere, and awaiting a communications upgrade.
Nov 07, 2011 - The answer to this inquiry, "I'm really rather impressed that I can just ask Wolfram a 7 day weather forecast and gives me the weather at my location..... This got my curiosity going as to where Wolfram gets this data." is here and involves CWOP.
Oct 19, 2011 - Regarding Thailand's worst floods in 50 years, this Bankok Post article tells of a local system where "The idea was inspired by the US government's Citizen Weather Observation Program that collects weather data from the public. The more citizens contribute data to the central system, the more accurate the picture of the water situation nationwide." Microsoft (Thailand) is working with a local partner to show how to apply a location-based information system to address the flood crisis.
Aug 30, 2011 - From Bill Morris, AR794, of the NWS Chicago WFO, "In the new storm spotter's guide there is mention of two volunteer programs -- CWOP, and CoCoRaHS beginning on page 13." Note the guide is a 27 MB download, but worth it.

Jan 06, 2011 - Nick Petro of the NWS Flagstaff Office recently registered weather station WX7FGZ-3 near the top of Agassiz Peak, one of the highest mountain peaks in Arizona. At 11,600 feet, this is the highest weather station that we have ever registered in CWOP. There's a ski resort (the Arizona Snowbowl) there. This weather station is located about 100 feet above the top of their highest chairlift and here's a youtube video with the weather station shown at the start and at the end. There's huge interest in this station by the ski folks there and people visiting the resort or hiking up on the mountain.
Jan 01, 2011 - Jim Roal DW3043 reports that Weather Station Data Logger is a fantastic open source project supporting CWOP. Currently it is for Oregon Scientific stations and some other sensors but that may soon be expanded. It is completely free and open source.
Nov 17, 2010 - During a recent damaging windstorm on the Olympic Peninsula in Washington State, the NWS reported that CWOP station AS753 reported the highest wind recorded, 72 mph.
