This last weekend I spent about 9 hours of quality time driving on interstates and state highways in Wisconsin. Here it seems (and maybe other states, too) there are what appear to be weather stations every so often along the road. A Rohn 25G tower, by the looks of it, is usually about 30' high, most of the time has an RM Young 5103 wind monitor on it, some sort of radiation shield with what I assume is a temp/humidity gizmo in it, and some times (rarely) a visibility device (really rare).
This last weekend I was surprised to see a tower that is so typical, but the wind device was not a Young propeller type monitor at all, but despite it going by so fast (my wife hates to loose time on the road) it seemed to be more like a cylinder with some sort of dome on the top, not your typical sonic anemometer at all.
Question:
Are these stations along all interstates?
Can the average public see what the stations are reporting, some sort of place for each state where, like the monitoring cameras where you can see traffic go by, you can see temps and wind and all?
Does anyone know if the basic installations are being updated with some newer stuff to get the data?
Thanks. Dale
