T107 Weather Station
1. Preparation and Siting
1.1 Siting and Exposure
If any part of the weather station comes in contact with
power lines, you could be killed. 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 in order to obtain
accurate meteorological data. In general, the site should be representative of
the general area of interest, and away from the influence of obstructions such
as buildings and trees.
The weather station should not be located where sprinkler irrigation water will
strike sensors or instrument enclosure.
Some general guidelines for site selection are listed below, which were
condensed from EPA (1988) 1 , WMO (1983) 2 , and AASC (1985) 3 publications.
1.1.1 Wind Speed and Direction
Wind sensors should be located over open level terrain, and at a distance of at
least ten times (EPA) the height of any nearby building, tree or other
obstruction, as illustrated in FIGURE 1-1.
