Station Metadata: Perry
The Orr station is located in Pike County at the University of Illinois Orr Agricultural Research and Demonstration Center located north and west of Perry on Illinois 104 between County Roads 2600E and 2800E. The tower is located 110 m southwest of the main buildings on a small knoll. The land surrounding the tower is rolling in all directions. Deciduous trees obstruct the wind flow from the northwest (45 m), north (30 m), and northeast (33 m). The trees closest to the station approach the 10 m height of the tower. Additional buildings are situated 135 m east of the tower and 125 m northwest of the tower. Mature deciduous forests are located 450 m southeast, 375 m southwest, and 350 m west of the tower. The exposure to the south is open, and the nearest obstruction is a single tree at a distance of 450 m. The position of the weather tower on the small knoll makes it susceptible to frequent lightning strikes.
