Gather the highest quality data with rapid, precise, and highly-configurable digital instruments chosen as the global standard.
Get real-time observations with fully-processed flux calculations effortlessly delivered with flexible data transfer options.
Gain ecosystem insights and get to publication faster with automated post-processing tools integrated for the first time into an intuitive user interface.
Analyzers and Instrument Platforms
Gather data confidently with the precision gas analyzers and instrument platforms that have been chosen as the global standard by top flux networks like Ameriflux, Asiaflux, Chinaflux, CERN, CARN, ICOS, and NEON.High-speed LI-COR digital gas analyzers have the lowest power requirements of any analyzers on the market and accommodate a variety of sonic anemometers and mounting structures to deliver proven performance and consistently reliable gas exchange data.
EddyPro® Software
Get real-time insights into your data with fully-processed fluxes on demand. Along with LI-COR instruments, EddyPro has been widely adopted by researchers and networks around the world, including the Integrated Carbon Observatory System (ICOS), the Chinese Ecosystem Research Network (CERN), Ameriflux, and many others.
Introducing: Tovi® Software
Get to ecosystem insights faster and more reliably than ever before. Tovi integrates powerful and widely-accepted post processing methods into a sleek, intuitive graphical user interface that provides the highest quality, publishable eddy covariance results.
A Complete System to Fit Your Research Needs
With a complete LI-COR system, you can be certain that your observations accurately reflect genuine differences in ecosystem-level gas exchange properties and that your results can be reliably interpreted. Submit your manuscript with confidence knowing that bias is not introduced by using other non-standard instruments or processing methods.
Eddy Covariance Software
EddyPro® Fluxsuite
LI-COR has developed unique data acquisition and flux computation, communication, and analysis software applications for every step in the eddy covariance research process. LI-COR eddy covariance systems compute flux results in real time with EddyPro® Software, which runs on the SmartFlux® System just as it does on your desktop computer. Your flux results are always online with FluxSuite™ software, and now, complete your analysis with Tovi™ software: a new suite of powerful eddy covariance post-processing tools.
The community standard flux processing software
EddyPro® Software is a powerful, free, and open source application for processing eddy covariance data. Developed in collaboration with the eddy covariance research community, EddyPro uses the most accepted and cited techniques to compute fully-processed fluxes of water vapor (evapotranspiration), carbon dioxide, methane, other trace gases, and energy, using the eddy covariance method.
EddyPro is widely adopted by eddy covariance researchers and research networks as their standard processing software, empowering the most accurate cross-comparisons of ecosystem fluxes around the world. The latest version, EddyPro 7, is the only processing software developed in collaboration with Fluxnet, Ameriflux, and the Integrated Carbon Observation System (ICOS), allowing you to consistently meet formatting standards for submission and future synthesis studies.
A brand-new main output file, named FLUXNET output, designed in collaboration with the ICOS, AmeriFlux, Fluxnet, OzFlux, and ChinaFlux teams to help you consistently meet their consolidated formatting standards. The FLUXNET output features a wide range of new output variables, including new intermediate results, statistics for all high-frequency variables, covariances between all high-frequency variable pairs, and biomet mean values and metadata. With the FLUXNET output, your EddyPro data will be primed for flux network post-processing with automated QC driven by jointly defined new tests, statistics, and variables.

Additional new developments in EddyPro 7 include:
- New raw data level filtering capabilities (wind direction filter)
- Improved wind direction statistics
- Compatibility with new Metek Multi-Path sonic anemometers
- New QC tests:
- Mahrt (1998) Stationarity Test1
- Novel Kurtosis Indexed on Differenced Variable (KID) Test
- Novel Fisher z-Test to detect dropouts and amplitude resolution issues
When using LI-COR .ghg raw file format, EddyPro 7 now produces the most self-documented, easy-to-process, and reproducible eddy covariance datasets. Effortlessly perform the critical corrections and calculations recommended or required by leading flux networks, and as always, get the same results and performance on your PC or with the EddyPro engine on the SmartFlux™ system.
