Canebas Weather Station uses a
Davis Vantage Pro-2 weather station for
the core of the weather instruments.
The particular model
model (
6152)
has the standard sadiation shield.
However, the actual temperature and
humidity data is supplied by a second
Davis temperature/humidity probe (model
6382)
that is located underneath a deck and
therefore completely escapes all solar
radiation. Below is a photo
showing the weather instruments including
an inset image of the temperature/humidy
probe:
As can be seen in the photo above, the
anemometer is mounted on a 10 feet high
mast above the roof. However, the
house is in the wind shadow of a hill and
tall trees. Therefore the wind data
does not represent the uninterrupted air
flow. All other data is believed to
represent the ambient conditions at the
station. The difference in
temperatures between the temperature probe
under the deck and the probe that is part
of the ISS unit is believed to be caused
by solar radiation heating and associated
warming from a concrete patio directly
underneath the ISS unit.
The wireless data is sent to a Davis
Weather Envoy
(model
6316)
which is connected to a MacBook Pro
(mid-2009). The Mac is running
OS-10.6.x (Snow Leopard) and the weather
software is
WeatherCat.
