It would be nice if Windy provided a way to see just pws stations on the map. It would be helpful to find neighbors,.compare data, etc.
There is a way to pull the entire database of Windy pws stations (non-madis) using your API key and you then get this nasty text dump file. The problem is that there is no CR after every record and the fields don't line up for every station as some have different columns. So it's a mess. I worked and manipulate the data in Excel and it wasn't easy nor fun. That dump file should be fixed. If you want to learn how to do it then read the API documentation. But you better know how to manipulate raw data, or it is just gibberish.
