Appendix DMeasurement Instruments

acoustic camera

microphone array that is used to localize and identify sound sources; can be two‐ or three‐dimensional

albedometer

device that measures the albedo, which is the proportion of light reflected by the Earth’s surface (%); typically consisting of two pyranometers, with one measuring the direct solar radiation and the other measuring the reflected radiation

anemometer

device to capture wind speed (m/s); may be a cup‐type, vane or hot‐wire anemometer

balances and scales

instruments that measure the weight of an object (kg)

carbon dioxide meter

device that captures the presence and concentration of CO₂; may be a non‐dispersive infrared (NDIR) or chemical sensor

carbon monoxide meter

instrument that detects the presence of CO; typical sensors are of the opto‐chemical, biomimetic, electrochemical or semiconductor type

chromameter

a device that measures the colour of surfaces

clamp meter

a meter that has two arms that ‘clamp’ around an electrical wire, allowing it to measure the electric current in that wire

electrical multimeter

device that measures electrical voltage (V or U), resistance (Ω) and current (I)

flow meter

device that establishes the flow rate of a liquid or gas (m³/s)

gloss meter

instrument that measures the specular reflection of a surface in Gloss Units (GU)

heat flux sensor

instrument that captures the heat flow in watts (W) through a surface

illuminance meter

instrument that captures the incident luminous flux in lux (lx) on a surface
