While we wait for an actual depiction of aerosol and low visibility, why not allowing users to manually adjust the maximum visibility with live weather.
Currently, with live weather, on a clear day, visibility is pretty much infinite, and granted it happens sometimes on very cold and clear days, most of the time, there are aerosols which limit the visibility.
It would be great if we could set a prefered maximum visibility with aerosol density even in live weather. So that, on a hot humid day for example, people can set their aerosols to a high value so the sky is nice and hazy even when there are no clouds, because currently the visibility would be infinite which is not realistic at all.
