NOTE

3.1 Siting

The rain gage should be mounted in a relatively level spot which is
representative of the surrounding area. The ground surface around the rain
gage should be natural vegetation or gravel. It should not be paved or
concrete.

For accurate measurements, the rain gage must be placed away from objects
that obstruct wind. The minimum distance should be 2 to 4 times the height of
the obstruction.
