eddy-covariance (EC) flux system for long-term monitoring of atmospheric-biosphere exchanges of carbon dioxide, water vapor, heat, and momentum. A complete system consists of a closed-path gas analyzer (EC155 closed-path gas analyzer), sonic anemometer (CSAT3A sonic anemometer), data logger (CR6 datalogger), sample pump, three-valve module that enables automatic zero and CO<sub>2\u00a0<\/sub>span measurements (manual H<sub>2<\/sub>O span), and accommodations for a CDM-A116 analog input expansion module allowing for additional sensors.<\/p><p>The gas analyzer\u2019s patented vortex intake design (United States Patent No. 9,217,692) and small sample cell volume (5.9 mL) provide a much lower flow rate than other closed-path systems while maintaining excellent frequency response (4.3 Hz cutoff frequency). Additionally, this design makes the system virtually maintenance free while still maintaining an ideal frequency response compared to traditional inline filters. Lower flow allows the CPEC310 to have one of the lowest total system power requirements (12 W) of any closed-path eddy covariance system. Campbell Scientific manufactures all components of the CPEC310, including the data logger and EasyFlux<sup>\u00ae<\/sup>\u00a0DL software for computing and correcting fluxes, which gives our system the most reliable functionality.<\/p><p><strong>Benefits and Features :<\/strong><\/p><ul><li>New conformal coating helps protect sonic transducers in corrosive environments<\/li><li>Expandable, high-end system with CR6 datalogger processing power and EasyFlux<sup>\u00ae<\/sup>DL software to compute and fully correct up to 20 Hz data<\/li><li>The three-valve module makes the CPEC310 the only closed-path eddy covariance system on the market with the ability to perform automatic zero and CO<sub>2<\/sub>\/H<sub>2<\/sub>O span<\/li><li>Additional port options for energy balance and atmospheric sensors<\/li><li>Ideal system for short or tall towers<\/li><li>Simple design provides easy use while maintaining full functionality<\/li><\/ul><h5>Detailed Description :<\/h5><p><strong>The gas analyzer\u2019s small sample cell volume (5.9 mL) minimizes the sample residence time (50 ms at the system\u2019s nominal flow rate, 7 LPM).
