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 ISS 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).

For more detailed siting suggestions, see Application Note #30: Reporting Quality
Observations to NOAA on www.davisnet.com/resources.
Optional: Cable Length Considerations
• All Vantage Pro2 stations include
a 40' (12 m) cable to go between
the ISS 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 ISS have been
installed on a site. Attaching the
anemometer cable to the
mounting pole using the supplied
cable tie is the recommended
option.
Keep the anemometer cable coiled
if possible during the ISS and
anemometer assembly so that it is
easily stowed once installation is
complete.
• The Cabled Vantage Pro2 includes a 100' (30 m) cable to go between the console
and the ISS. This can be extended up to 1000' (300 m) using optional cables.
