Missing SYNOP stations

wetterheidi

Since a few weeks I'm missing the SYNOP data of several German SYNOP stations.
For example: 10961 Zugspitze, 10962 Hohenpeissenberg, 10982 Chieming and a lot more.
Is this a bug or a feature? ;-)

@wetterheidi Hello, thank you for noticing, we will try to update the SYNOP database in the future.

@korina just noting these are still missing

there's a ton of personal weather stations, but then those are not a good replacement for the quality-controlled SYNOP stations

I am pretty sure you would get those via the DWD feed, but I dont envy anyone working with https://gisc.dwd.de/wisportal

@mhaberler Hello, we will try to add them as soon as we can.

Hi @Korina

@wetterheidi and me looked a bit more into the issue

In case the raw data feed is missing:

the German SYNOP reports are available via https://gisc.dwd.de/wisportal/ via the subscription German_Reports_SYNOP ("Internet Subscriptions -> Default Carts -> German_Reports_SYNOP"). Those are in the BUFR (FM94) format, very similar to what @Filip_K is already retrieving for the radiosonde data

here is one example member of the German_Reports_SYNOP dataset - it contains two of the stations Heidi mentioned to be missing:

can be found on https://gisc.dwd.de/wisportal/ via the search term "GTS Bulletin: ISID03 EDZW - Observational data (Binary coded) - BUFR (details are described in the abstract)"

Chieming is in "GTS Bulletin: ISGD09 EDZW - Observational data (Binary coded) - BUFR (details are described in the abstract)"

@korina in case the feed is in place, but the station numbers are missing and that happens to be the reason why the stations are not shown:

I feel with you as getting an official and well-curated list of WMO station id's and related information is next to impossible, it is a real mess - I started my own curated list for the radiosonde project, adding missing stations piecemeal

However, there is an interesting project which already maintains such a list of stations in JSON format and I'm considering using this list, after adding any missing pieces and then switching to it

Maybe you'd want to discuss internally if you want to switch as well, or fork it at https://github.com/windycom ?

this list is pretty comprehensive, easy to process and it should be in pretty good shape if maintained by several parties

@mhaberler @wetterheidi Hello, our team will look into this further, thank you for additional information and sources.

@mhaberler @wetterheidi thank you for your input!
The stations you have mentioned are back, see https://www.windy.com/station/wmo-10982?47.883,12.533,8 https://www.windy.com/station/wmo-10962?47.798,11.019,8 and https://www.windy.com/station/wmo-10961?47.417,10.981,8

We will continue to process your list of stations in order to have as much as possible WMO stations at Windy.

@kekert thanks for fixing this - already much better!

mhaberler

@kekert is it just my gut feeling that there are more WMO stations being displayed now in general, not just Germany?

kekert

@mhaberler yes, we are processing more now (as we added more sources, fixed some bugs & upgraded packages)
