Bresser 7-1 National Geographic WLAN 9080600

[Massimo Giuseppe Maldarizzi]

Good evening I'm a radio amateur and I have a weather station "Bresser 7-1 National Geographic WLAN 9080600" connected to the internet and I wanted to provide the data to CWOP. 
Can anyone help me set up the station or tell me how I can pass my station data to CWOP ?
Thank you

I doubt there is reasonable way to accomplish this with this station. It's software appears to only know how to support three different mesonets and it does not look like there is a way to access the raw data directly.

There are a few "unreasonable" way to do it:

• Send the data to Wunderground. Create a separate program on a computer which downloads the data from Wunderground every 5-minutes or so, then reformat it and uploads it to CWOP.
• Set up a reverse proxy server that intercepts the HTTP/S traffic that is being sent to one of the three mesonest it knows how to work with, make a copy of the data it's sending before forwarding the traffic to the intended endpoint, then use the copy captured at the proxy server to format a message you can send to CWOP.

It boils down to either accessing the data after it's been sent somewhere else, or, intercept is in transit. Neither is trivial for most people.

Also, you mentioned you're an Amateur Radio operator (HAM). Was your intention to send the data over RF? That's a whole other conversation if that's the case. which starts with no.

Will CWOP even take overseas data?

Yes absolutely, but currently, stations reporting from outside North America are sparse by comparison.

If you are sending data to Wunderground already, you could use my script:

https://github.com/leoherzog/WundergroundStationForwarder

That script can forward onto CWOP and other services automatically, free and hosted.

In thanking you all for your emails, I confirm that my station already passes all data to Wunderground. Wouldn't it be simpler to take the code (API KEY) that the Wunderground site provides and automatically pass it to CWPO as all sites require to retrieve data from this type of station? It would be simpler and would increase the number of weather stations around the world that collaborate with CWPO

Well, CWOP was started more than 20 years ago by a group of Amateur Radio operators who had already established a digital packet network over RF using the Amateur Packet Reporting System (APRS) protocol which they devised for that purpose. Weather data was just another data type that was added to the APRS specification. So, the weather data traversing the APRS radio network was aggregated and sent over to the Meteorological Assimilation Ingest System (MADIS) at the National Oceanic and Atmospheric Administration (NOAA), which is a US Government entity. So, CWOP is crowdsourced weather data that's aggregated with an obscure, complex protocol, the primary purpose of which is implementing a meshed RF digital network, although there are APRS Internet Gateways (APRS-IS) which allow RF traffic to be gated to the Internet as well as being gated back again. The weather extensions of the APRS protocol haven't changed in any material way since they were first implemented more than two decades ago. There are no commercial entities involved who would drive strategic direction.

Yes, there are far simpler and extensible ways to aggregate a large number of stations using modern technology. But, if you stood that protocol up today you'd have 0 stations using the new protocol and more than 15,000 using the old one. Consequently, there isn't much appetite to move away from something that's been so widely adopted for so long without offering a compelling reason to all the parties who've invested so much in the existing protocol.

Also, the opposite is true. MADIS not only aggregates data from a long list of mesonets, but it also disseminates that aggregate data to other entities both commercial and private. Wunderground happens to be one of those entities. Any data you send to CWOP ends up on Wunderground, but data you send to Wunderground does not go the other way. If you send data to both you need to go into your Wunderground profile and add your CWOP id, otherwise Wunderground will show both stations, duplicating your data.

[Ted Lum]

It looks like wunderground may have made a change; I no longer see the CWOP ID under the user profile. I'm not sure when they changed it, but id does look like its no longer there. I'm also not sure what their strategy is for suppressing duplicate stations since they seem to have eliminated the ability to explicitly associate them.

yes but technically where do I go to insert CWOP ID on Wunderground?

All,

 

This concept of legacy formats persisting far beyond their intended purpose reminds me of SHEF (Standard Hydrometeorological Exchange Format). 

In 1981 a group of hydrologists at the Portland River Forecast Center were faced with creating a data format that would transmit hydromet data on AFOS (Automation of Field Operations and Services) which replaced teletypes.

This was an ASCII format that needed to be visually and machine readable.  It was constrained by the national 4800 baud rate used to transmit information on AFOS.  The original formats were done on IBM FORTRAN coding forms.

 

When we began, we were restricted to a two digit year.  We commented to NWS HQ that a four digit year would be needed in 20 years to avoid Y2K issues.  NWS HQ stated that an extra two characters for a four digit year would overload the system.  We looked at each other and said, surely there will be another format to replace SHEF by then.  Nope.  The format continues to be used for a myriad of public messages that are easily decoded by FORTRAN, PYTHON, JAVA or any number of text processors. 

 

Back in 1981 we had no distractions and focused on the core requirements for transmitting hydromet data.  In the end a simple design can live forever and in this case it does.

AS far as I can tell, WU stopped using CWOP data a while [a few years?] ago.  I have to upload to them separately - in addition to CWOP.  Thus there's no need to suppress duplicates anymore.  Example: I send DW2257 to both CWOP and WU.  No dup shows up on WU, and there's no place in the WU station config to enter a CWOP ID.

I believe that happened soon after IBM bought Weather Underground (as part of IBM's purchase of The Weather Channel) in 2016.

All,

This is a bit confusing.  I upload my Davis Vue Pro 2 data to CWOP and WU using CUMULUS every 5 minutes.  Both servers display my data.  Additional research is warranted.
