This section describes briefly the installation and proper grounding of the base tower (UT10) that will
house all the equipment for the climate station. More detailed instructions can be found in the manual
for the base tower (http://www.campbellsci.com/documents/manuals/ut10.pdf).
5.3.1 Base Installation
The tower is based on top of a concrete foundation that must be installed at the site. It is very important
to install the base of the tower correctly since all of the equipment will be attached to the tower.
Because of this, any errors in the installation of the base can potentially cause errors in the collection
of data. Although most of the equipment can be calibrated to account for small errors in the orientation
of the tower, it is best to install the base according to the procedure below. More details can be found
on page 2-1 of the UT10 manual.

Assemble four 5 x 10 x 61 cm pieces of lumber in a square
and place the square on the ground above the hole so each side is resting on top of the hole’s
edge. The middle of the square should be centered over the hole in the ground and any space
between the wooden frame and ground should be filled so concrete does not leak out of the
sides.

Put four stakes around the wooden foundation frame in order
to secure it. The wooden square and stakes will provide the base of the concrete foundation.

Mix the concrete together with rocks and sand. Fill the hole
with the resulting mixture until it reaches the top of the wooden frame.

Let the concrete settle for about two hours and then drive the
anchor bolts most of the way into the hole, leaving room so the base does not sit directly on
top of the wet concrete. Adjust the orientation of the base so one of the corners of the base is
pointing to the north. Using a level, ensure that the base is not tilted. Once the concrete
hardens (wait for at least 24 hours), the base can be further leveled and tightened using the
attached nuts.
