Economical, Easy-to-Install, Excellent Soil Contact
Expandable Closed-Path Eddy-Covariance System with EC155, Pump Module, and Automatic Zero and Span
EasyFlux™ DL is a free CRBasic program that enables a datalogger to report fully corrected fluxes of CO2, latent heat (H2O), sensible heat, and momentum from a Campbell Scientific open-path eddy-covariance (EC) system. Final fluxes are processed from raw high frequency time series data by applying commonly used corrections found in scientific literature.
Campbell Scientific’s IRGASON fully integrates the open-path analyzer and sonic anemometer. Designed specifically for eddy-covariance flux measurements, the patented design is easier to install and use than separate sensors and provides increased measurement accuracy. The IRGASON simultaneously measures absolute carbon dioxide and water vapor, air temperature, barometric pressure, and three-dimensional wind speed and sonic air temperature.
The CPEC200 is a closed-path eddy-covariance system that measures surface-atmosphere exchange of carbon dioxide, water vapor, heat, and momentum. The system includes Campbell Scientific's EC155 closed-path gas analyzer, our CSAT3A sonic anemometer, and our CR3000 datalogger, along with the other hardware and software needed for a turn-key eddy-covariance system.
Campbell Scientific’s EC150 is an open-path analyzer specifically designed for eddy covariance flux measurements. Combined with the CSAT3A sonic anemometer as shown above, these two components of an open-path eddy-covariance system simultaneously measure carbon dioxide, water vapor, air temperature, barometric pressure, and three-dimensional wind speed and sonic air temperature.
Campbell Scientific’s CSAT3 3D Sonic Anemometer is the 3D sonic anemometer of choice for eddy-covariance measurements. It has an aerodynamic design, a 10 cm vertical measurement path, operates in a pulsed acoustic mode, and withstands exposure to harsh weather conditions. Three orthogonal wind components (ux, uy, uz) and the speed of sound (c) are measured and output at a maximum rate of 60 Hz. Analog outputs and two types of digital outputs are provided.
