TEAM Climate Monitoring Protocol 3.0

This document describes in detail all the necessary steps to setup and implement the TEAM

Climate Monitoring Protocol. It has been written with non-experts in mind, so that anyone with

basic technical skills can understand the process of assembling a climate station and collecting

consistent and reliable climate measurements in tropical forests.

2 GOALS AND IMPLEMENTATION

The goal of the TEAM Climate Monitoring Protocol is to provide a standardized methodology to

generate high-quality reliable measurements of climatic variables in tropical forests. There is a

trade-off between the financial investment for the infrastructure (i.e. physical foundation,

sensors, equipment, etc) of the climate station and the level of high quality scientific data

captured. With this trade-off in mind, TEAM has designed two separate climate protocols that

differ in their initial investment in infrastructure and equipment but maximize the reliability and

quality of the data generated (a ground-based protocol and a canopy-tower based protocol).

This document describes a ground-based protocol where all the instrumentation is installed in a 3

m tower located in an adequate-size clearing. This ground-based version of the TEAM Climate

Monitoring Protocol implements measurements for four climatic variables: air temperature,

relative humidity, precipitation and global solar radiation. The sensors used, are mid-priced

ranged, but sensitive and reliable enough to handle the rough conditions encountered in tropical

environments. The climate station operates automatically; the sensor data feeds into a data

logger, powered by a solar panel and a rechargeable battery (for night operation). The data

logger collects information from the sensors every 5 seconds and produces summaries every 5

minutes (see Box 1 for a quick description of the protocol).

Box1. TEAM Climate protocol in a nutshell

• Climate station is ground-based (most equipment mounted on a 3 m tower)

• Climate station is autonomous and self powered (solar panel, battery)

• Four variables measured: Air Temperature, Relative Humidity, Global Solar Radiation,

and Precipitation

• Sensors for temperature/relative humidity and solar radiation are run in duplicate

• Temperature/RH sensors housed inside an aspirated radiation shield

• Measurements are logged every 5 seconds and reported every 5 minutes in a data logger

• Automated standardized computer program for data collection

• Detailed maintenance and sensor calibration schedules that are incorporated into the

metadata
