DANGER:
If any part of the weather station comes into contact with power lines, death or serious injury
could occur. Contact local utilities for the location of buried utility lines before digging or
driving ground rods.
Selecting an appropriate site for the weather station is critical to obtain accurate meteorological
data. In general, the site should be representative of the area being studied, and away from the
influence of obstructions such as buildings and trees.
Do not place the weather station where sprinkler irrigation water will strike the sensors or
instrument enclosure.
