TEAM Climate Monitoring Protocol 3.0
5.2.1 Base Installation
The tower is based on top of a concrete foundation that must be installed at the site. A square
hole of 61 cm on the side and 61 cm deep must be dug out and a concrete foundation built out of
a 5 x 10 x 61 cm lumber square (inside dimensions). The square and 4 stakes centered around
each side will provide the base for the concrete foundation. The anchor bolts and base of the
tower are assembled, the hole is filled with concrete and the anchor bolts are driven in with the
tilt base. Wood strips should support the base so it does not sit on top of the wet concrete. Once
the concrete hardens, the wood strips are removed and the base is leveled and tightened with the
attached nuts (see more details in page 2-1 of the UT10 manual).
5.2.2 Tower Installation
After the tilt base is installed the rest of the tower can be assembled and positioned. First install
the mast on the top most section. Then slide the three tower legs into the sleeves of the base.
Level the tower by adjusting the leveling bolts (see more details in page 2-2 of the UT10
manual).
5.2.3 Grounding
PROPER GROUNDING IS CRITICAL TO PROTECT THE INTEGRITY OF ALL THE
EQUIPMENT against lighting strikes. First drive the ground rod next to the base of the tower
using a sledgehammer. Then attach one end of the ground cable (4 AWG wire) to the rod and
then route the cable and attach to the tower leg using the clamp. Route the green (12 AWG ) wire
upwards to where the instrument enclosure will be installed (see more details in page 2-3 of the
UT10 manual). See sections 5.6 for details on grounding the enclosure and the data logger.
5.3 Installing the Data Logger and Battery
The data logger (CR1000) should be installed in a weather resistant enclosure that is attached to
the side of the tower (ENC 14/16). First install the data logger into the enclosure and then attach
the enclosure to the tower. The data logger should be mounted low on the enclosure and secured
to the backplate with 4 screws. This should leave plenty of the space below the data logger for
the incoming cables from the sensors, power cables and the ground cable. The enclosure can be
mounted to the side of the tower by using the mounting brackets attached. Mount the enclosure
at about eye level to facilitate access to it (see more detailed instructions in page 3-1 of the UT10
manual).
The battery should NOT be installed inside the enclosure; lead-based batteries will leak small
amounts of hydrogen gas when charged, creating a potentially dangerous fire hazard in the
absence of appropriate ventilation. To protect it from the elements, the battery should be placed
in a separate plastic/metal container with slits/holes to allow airflow (a plastic car battery
enclosure can be purchased locally). The battery and its enclosure can be mounted on the side of
the tower or sitting on the ground and appropriately secured (e.g. chained).
5.4 Installing the Solar Panel
The solar panel should be installed in a way to maximize exposure to sunlight and ensure the
station can run on solar power during the day.
