About weather stations at Windy
We gather data from more than 30.000 weather stations. They fall into one of this category:
Professional weather stations run by government agencies. Stations report weather observed in the form of SYNOP codes usually once in an hour, and even less. The latest observation is available sometimes quite late after measurement. The quality of observation is very high. Each station is identified by file number code, for example
11518is Prague Ruzyne.
Professional weather stations run by airport operators. Airports report observed weather in the form of METAR codes usually once in an hour or less, and the observation is available to us immediately. The quality of observation is very high. Big airports report the same weather also in the form of SYNOPs (in other words there are "two stations" at the same place). Each airport is identified by four-letter ICAO code, for example
LKPRrepresents airport in Prague.
Corporate and enthusiasts weather stations
Small weather stations, connected to the Internet and run by companies or individuals, we interest in meteorology. They report observation quite often (usually every 5 minutes), and quality is reasonably good. A lot of them have wind sensor, but it can be (in many cases) placed in the wrong location.

It seems that some WMO stations in Germany vanished from the windy map some days ago. For example, there is nothing anymore in the Berlin area --- in the past, there used to be at least Berlin-Dahlem, Berlin-Tempelhof and Grünow (I think the respective wmo numbers are 10381, 10384, and 10289).
@eserte Hello, they might have been removed from the database.
@korina Hopefully not --- Dahlem and Tempelhof were the only official (non-madis and non-pws) weather stations in Berlin.
The stations still exist, other weather sites still show data for them.
