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).
Note: For more detailed siting suggestions, see Application Note #30: Reporting Quality
Observations to NOAA in the support section of www.davisinstruments.com
• All Vantage Pro2 stations
include a 40' (12 m) cable to
go between the sensor suite
and the anemometer. This can
be extended up to 540' (165
m) using optional extension
cables purchased from Davis
Instruments.
If most of the anemometer
cable length is unused, the
coiled cable length can be
stowed once the anemometer
and sensor suite have been
installed on a site. You can
secure the cable to the pole
using the shorter cable ties.
Use the longer cable tie to
secure the coil by running it
through the holes on the rain
collector shelf.
Keep the anemometer cable
coiled if possible during the
sensor suite and anemometer
assembly so that it is easily stowed once installation is complete.
