Anemometer Siting Guidelines
• For best results, place the anemometer at least 7' (2.1 m) above surrounding
obstructions such as trees or buildings that obstruct wind flow.
• If mounting on a roof, mount the anemometer at least 7' (2.1 m) above the roof
apex. (When using a Davis Mounting Tripod, install the anemometer at the very
top of the pole).
• If mounting the sensor suite and the anemometer together, such as on a pole or a
wooden post, mount the anemometer so it is at least 12'' (0.3 m) above the top of
the rain collector cone for best results.
• The standard for meteorological and aviation applications is to place the
anemometer 33' (10 m) above the ground. Seek professional help for this type of
installation.
• The standard for agricultural applications is to place the anemometer 6' (2 m)
above the ground. This is important for evapotranspiration (ET) calculations.
Note: For roof mounting, and ease of installation, we recommend using the optional mounting
tripod (#7716). For other installations, use the Mounting Pole Kit (#7717).
