How does EPW files being added to the epwmap ? Are they being added by all the users ?
If there a solution if there is no epw data in a city that we need by chance ?
No they are not.
Please check the following posts. They have several resources listed for weather data.

If none of the above works for you, then you will have to use available weather data for a similar weather type (Not necessarily the nearest).

Thanks for the comprehensive answer, @devang . In addition to those resources, I know that @josephyang is looking for beta testers for a web API that can provide approximate climate data for essentially everywhere on the planet:
So that’s a particularly good option if all of the other sources aren’t suitable.
Super !
Climate.OneBuilding.Org is so great.
Just need to download the relevant region [i.e. WMO Region 6 - Europe] and drag it into Google Earth.
Why not just use the LB_DownloadEPW component? It will take you to a map where you can pick the location.

In the epwmap site, sometimes you will not find the epw file for some cities, especially in Europe, very few cities has the epw file for downloading.
Another source for European cities is https://rokka.shinyapps.io/shinyweatherdata/ - although it’s limited to 2016 only and only for Northern Europe for the time being, it works very well and you can specify the radiation data source.

The reason why you don’t see certain EPW files in EPWmap that is that OneBuilding is constantly adding new files to its database but we only update EPWmap every ~6 months or so. So, at a certain point, EPWmap should have all of the file you see in the KMZ but you would be right that the KMZ is the “latest and greatest” version of the OneBuilding database.

The https://rokka.shinyapps.io/shinyweatherdata service is now updated with ERA5 global reanalysis climate data from Copernicus/ECMWF. Global coverage and data from 1980 until recent time. Fast access to long time series, formatted as CSV files or EnergyPlus EPW files.
CAMS satellite derived solar radiation data available as well, covering Europe, Africa and Middle East (roughly -66° to 66° in both latitudes and longitudes).

Thanks @josephyang! Went for my own storage solution for the historical data (I want to add things like TMY and extreme periods identification, which requires access to the whole dataset). But I might use your excellent service at https://oikolab.com to keep it updated with more recent data.
That’s fantastic that you updated your app - now I don’t have to create one myself.
