Why Use Eddy Covariance to Measure Flux?
The eddy covariance technique is the most widely used, accurate, and direct method presently available for quantifying exchanges of carbon dioxide, water vapour, methane, various other gases, and energy between the surface of earth and the atmosphere.
Eddy covariance provides an accurate way to measure surface-to-atmosphere fluxes, gas exchange budgets, and emissions from a variety of ecosystems, including agricultural and urban plots, landfills, and various water surfaces. Emissions and fluxes can be measured by instrumentation on either a stationary or mobile tower, floating vessel (such as a ship or buoy), or aircraft.
Summary of Eddy Covariance
• Quantifies gas exchange rates, emissions and fluxes by directly measuring movement of gases in the air
• Requires turbulent flow, with winds generally above 0.5 m/s
• Requires state-of-the-art fast instruments
• Most direct and defensible way to measure flux

Portable Photosynthesis System
Brand : Li-Cor
LI-6400XT Portable Photosynthesis system
The LI‑6400XT has two absolute CO2 and two absolute H2O non-dispersive infrared gas analyzers that provide superior performance in a field-portable system.The gas analyzers are in the sensor head, which allows for real-time measurements with leaf-level environmental feedback control. This is not possible when analyzers are in the console.
NEW !!! PORTABLE PHOTOSYNTHESIS SYSTEM
LI-6800 Portable Photosynthesis System
The only instrument in the world that uses Rapid Sensing™ Technology for fast A-Ci curves and survey measurements.
Soil Gas Flux System
Designed to minimize effects on the variables you want to measure, LI-8100A chambers are the result of close collaboration between scientists and engineers.
- Equalize pressure in the chamber with atmospheric pressure—even in windy conditions
- Chamber shape provides a well-mixed air sample
- Constructed from durable components—for long-term outdoor deployment
The long-term chambers pivot away from the measurement area to minimize alterations to sun exposure, wind, and precipitation at the sample location. They have user-selectable open positions for situations where it is necessary to avoid terrain or other obstructions
The opaque long-term chamber (8100-104) is finished in durable, highly reflective white enamel.
10-cm Survey Chamber
The 10-cm survey chamber (8100-102) features durable white enamel finish. It is designed to be easy to move from one point to another, for surveying and mapping CO2 concentrations. Ideal for sampling small areas between plants or other obstructions.
Clear Long-Term Chamber
The clear chamber (8100-104C) is designed for long-term net carbon exchange measurements. It features a durable, clear chamber so that plants are exposed to sunlight during measurements.
20-cm Survey Chamber
The 20-cm survey chamber (8100-103) features durable white enamel finish. It is designed to be easy to move from one point to another, for surveying and mapping CO2 concentrations. High sample area-to-perimeter ratio provides a good representation of undisturbed soil.
LI-3100C Area Meter
The LI-3100C Area Meter is designed for efficient, exacting measurements of both large and small objects. User-selectable area resolution of either 1 mm2 or 0.1 mm2 is available without having to change optics. This versatility provides the flexibility necessary for diverse project requirements.
LI-3000C Portable Leaf Area Meter
The LI-3000C combines an easy-to-use readout console with the proven scanning technology of the LI-3000C sensor head to provide a powerful system for portable, non-destructive leaf area measurements. It utilizes an electronic method of rectangular approximation to provide 1 mm2 resolution. Leaf area, leaf length, average width, and maximum width are logged by the readout console as the scanning head is drawn over a leaf. Files can be viewed on the display or output to a computer using the LI‑3000C application software.
LAI – 2200C Plant Canopy Analyzer
World standard for
indirect LAI measurements
The LAI‑2200C Plant Canopy Analyzer uses a non-destructive method to easily and accurately measure Leaf Area Index (LAI). It consistently outperforms other methods such as Ceptometry and Hemispherical Photography in terms of flexibility, advanced features, accuracy, and ease of use.
