Data Logger Program/Script. Compiled script or computer program that instructs the data

logger where each sensor is connected, the frequency of data collection (e.g. every 5 sec), the

interval of measurement report (e.g. 5 min), and what to do with the different variables for

each interval (e.g. calculate an average, total, minimum, standard deviation, etc). TEAM uses

a standardized script to ensure data collection is uniform across climate stations in the

network.

Data Management Tool. An internet portal that is used for uploading data. The system

stores all of the information that is required by this protocol in an easy to access system. In

addition to storing site maintenance and spatial information, there are also separate tabs for

describing the site, uploading images, managing sensors, and recording height profiles as

well as heavy rainfall events.

Data Upload. Process of transferring information (from a data logger, Excel sheet, a

maintenance log, etc) to the TEAM portal through a predefined process (e.g. DeskTEAM).

The data received is checked for basic consistency before being incorporated into the TEAM

database.

Enclosure. Special box that houses the data logger and other sensitive components of the

climate station.

Grounding. Process to protect the climate tower from lightning and/or the accumulation of

static electricity. The base tower is protected with a rod that routes potential lightning strikes

to the ground through a 4 AWG cable (copper cable 5.19 mm diameter). The data logger and

enclosure are also grounded to this same cable to discharge them from static electricity

through a 12 AWG cable (copper cable 2.05 mm diameter).

Memory Card. Device to store climate data collected by the data logger (usually a 32-64

MB Compact Flash card). The data logger partitions the memory card in a special way to

maximize the amount of data stored.

Metadata. Data about other data. In general, metadata is structured or standardized using a

scheme to capture it and make it interchangeable and easily readable. Climate metadata

includes details about the sensors (e.g. type, make, model, calibration, etc.), the data logger

(model, firmware version, etc.), the climate station (latitude, longitude, start date,

maintenance information records). TEAM uses the XXX metadata standards.

PC200W Software. Software provided by Campbell Scientific to program a data logger,

extract data from it and visualize it. TEAM uses PC200W to initially setup the time in the

data logger, load the TEAM climate data collection script and extract data from the data

logger or a memory card.

Precipitation. Quantitative measurement of rainfall during a specified time interval. Rainfall

is usually measured in linear units (e.g. mm/time) to standardize for capture area; volume of

water (cm

) / area of capture (cm

) per unit time × 10. TEAM uses a tipping bucket that

sends a pulse signal to the data logger for every 0.2 mm of rain captured.
