TEAM Climate Monitoring Protocol 3.0

3 BASIC EQUIPMENT DESCRIPTION

In order to be an adequate tool for monitoring climate, the sensors and equipment used in the

Climate Protocol must comply with minimum standards of quality and accuracy required by

other standard climate monitoring efforts (e.g. United States Climate Reference Network at the

National Oceanic Atmospheric Administration). The following section describes briefly each of

the components required to implement the TEAM Climate Protocol. A list of the equipment

with providers and model numbers can be found on Appendix A.1. The range, resolution,

required uncertainty and other technical specifications for the variables measured in the TEAM

Climate Protocol are summarized in Table 1.

3.1 Base -UT10 tower

The base of the climate station where the data logger, power sources and sensors (except

rainfall), are located, consists of a 3 m aluminum tower. We recommend the use of Campbell’s

Scientific UT10 tower, which is light (18 kg), requires a small footprint for installation (61 x 61

x 61 cm) and has a high wind load (177 km/h). The tower comes with a grounding kit to protect

the integrity of the equipment and data during lighting storms.

3.2 Data logger -CR1000

The data logger receives all the information from the sensors and organizes the data that can be

exported later to a computer, memory card or broadcasted through a radio signal or network. The

protocol requires a data logger that can accommodate a wide array of sensors, is expandable, is

fully programmable, has network communication capabilities, and is rugged for the conditions

encountered at tropical forest sites. An adequate data logger that fits these specifications is the

CR1000 (Campbell Scientific). More detailed information on how to setup, program, maintain

and retrieve data from the CR1000 is found in later sections of this document (sections 5.1, 6.1,

6.3)

3.3 Sensors

The 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. The data

logger receives this information and transforms it into the measurement of the variable in a

suitable unit (e.g. ºC, mm). The protocol uses sensors to measure four climatic variables: Air

Temperature (in duplicate), Relative Humidity (in duplicate), Precipitation and Global Solar

Radiation (in duplicate). The location of the climate station near the ground does not allow for

reliable measurements of wind speed and velocity (see section 4, for detailed climate station

siting requirements for different sensors). The sensors used in the TEAM Climate Protocol are

described below in more detail.
