. Device that reflects solar radiation to shield it from a sensor (usually a
temperature sensor). TEAM uses an aspirated radiation shield (MetOne) that actively isolates the
sensor chamber wall from external direct solar radiation by driving air from the bottom of the shield
through a fan. Passive radiation shields do not actively isolate the sensor chamber but instead rely
on a series of interconnected hollow plates that shield the air heated by the external radiation.

Variable that measures the ratio of the actual vapor pressure in the air with
respect to the saturation vapor pressure. The relative humidity is expressed as a percent.

The sampling unit is defined as the smallest indivisible unit of the total
population selected for sampling. The two major types of sampling units used in TEAM are points
and areas. The sampling unit for the TEAM Climate Protocol is a point.

Sensors are the instruments that make the actual measurements of given climatic
variables. Suitable sensors accurately translate environmental change into measurable electrical
properties by outputting a voltage, changing resistance, outputting pulses, or changing states.

Field form to keep track of sensor calibration information such as
date when sensor was sent for calibration, serial numbers of sensor in calibration and replacement
sensors, etc. All information from the Sensor Calibration Form needs to be uploaded to the TEAM
portal where it will be stored as downloadable metadata.

station as a function of physical characteristics of the site, height and distance from obstacles,
specific sensor requirements, etc. The siting process is decribed in detail in Section 4 of the TEAM
Climate Protocol.

A device that captures solar energy and transforms it into electrical energy. In the
context of the TEAM Climate Protocol, this energy is used to power the data logger, sensors and
radiation shield. The solar panel also charges the battery so that it can power the station at night or
during cloudy days. We recommend the use of a 40W-2.2 Amp solar panel to fulfill the power
requirements of the climate station.

Is the amount of energy in the form of electromagnetic waves coming from the
sun. Radiation from the sun spans a wide range of frequencies from the Ultra violet (100-400 nm)
passing through the visible light (400-700 nm) and the infrared or heat (700 – 10
6
nm).

. Device to estimate rainfall automatically without human intervention. A tipping
bucket collects rain through a funnel that fills one side of a bucket that is pivoted in the middle. As
one side of the bucket fills with water the weight drives it down releasing the water and causing the
bucket to tip to other side, where the process starts again. Each tip is recorded by the data logger
as a pulse signal and is equivalent to a fixed amount of rain (usually 0.1-0.2 mm).
