Table 1. Suggested tilt angle to maximize incident solar radiation year round (modified from Landau 2001).

Note: Use a clinometer to ensure the correct tilt angle. For example, it the station is located 15

degrees north of the equator, the solar panel should be facing south and angled at 20 degrees

from the horizontal.

3.14 Installing the sensors

Equipment/supplies needed:

• Pen/Pencil

• Blank Sensor Calibration Form

There are two main steps involved in the installation of the sensors: first, the sensor should be

adequately positioned on a mounting bracket and attached to the tower and then the cable from

the sensor should be connected to the data logger. Below, we describe the main steps to mount

each sensor. Refer to the documentation enclosed with each sensor for more detailed

instructions. Record the serial numbers and activation times for each sensor installed because

this information will need to be uploaded to the TEAM portal upon return from the field. The

Sensor Installation/Calibration Form can be used to record this information. Fill in all of the

required information (i.e. date, activation time, recording person, serial number, etc.) and keep in

mind that this form is also used when removing sensors for calibration, so make a note that these

sensors are being installed for the first time on the field form.

3.15 Vaisala HMP45C Temperature/RH sensor

Equipment/supplies needed:

• Electrical Tape

• Permanent marker

• Wire cutter/stripper

• Phillips’ screwdriver

• Plastic cable ties

• Two Temperature/RH sensors (HMP45C)

• Aspirated Radiation Shield (076B)

Two HMP45C sensors are housed inside a passive radiation shield. Follow these steps to mount

the shield and the sensors inside it.
