Or at best I would have had wires at neck-level in the house. It's reading a good quarter inch off from the NWS gague in the yard. I'm still getting some odd readings, and not sure what to attribute them to. Sunlight could be heating the Stevenson Screen, but it is in the shade itself, and is built to specs and painted white. The other possibility is that warmer air is coming from the apartement in the basement.
Further study is needed.
The whole thing tries to turn around sometimes, and the anemometer must always face South or the direction readings will be off. Strapping over the wing nut seemed to help. The pipeset could come detached from the wall. If it did, I'm not sure if it would hit the railing or be strangled by the anemometer wire first. In any case, it wouldn't be too good for the instrumentation.
