TEAM Climate Monitoring Protocol 3.0

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.

Pyranometer. Instrument to measure the heating power of radiation, in particular of

radiation coming from the sun (300-2800 nm). The pyranometer measures solar radiation

flux density (watts/m

) from a field of view of 180 degrees. Solar radiation measurements

usually vary as a function of sun position, season, cloud cover, atmospheric composition and

any other physical/chemical variables that filter irradiance.

Radiation Shield. 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.

Relative Humidity. 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.

Sampling Unit. 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.

Sensor. 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.
