It's a Davis vantage pro 2, so yes, aspirated and radiation shield. But the issue is the siting sucks, scientifically speaking. In order to provide physical security at UMass we elected to put it on the edge a low rooftop. It's not black tar, but it runs a little hot from the surroundings, and UMass is a pit as it is.
