Eddy Covariance Processing Software | Version 5
EddyPro® is a powerful software application for processing eddy covariance data. It computes fluxes of water vapor (evapotranspiration), carbon dioxide, methane, other trace gases, and energy with the eddy covariance method.
EddyPro is available for free download from LI‑COR Biosciences:

EddyPro is an open source software application developed, maintained and supported by LI‑COR Biosciences. It originates from ECO2S, the Eddy COvariance COmmunity Software project, which was developed as part of the Infrastructure for Measurement of the European Carbon Cycle (IMECC-EU) research project. We gratefully acknowledge the IMECC consortium, the ECO2S development team, the University of Tuscia (Italy) and scientists around the world who assisted with development and testing of the original version of this software.

Recent Advancements Include:
- Support for the SMARTFlux system, for real-time fluxes computed in the field using Advanced or Express settings
- Integrate data from biological and meteorological (biomet) sensors at your site (ambient air temperature, relative humidity, global radiation, etc.) into your flux computations
- Comprehensive spectral assessment using both analytical and in situ methods
- Built on the proven IMECC* platform with easy-to-learn and simple interface
- Seamless processing of LI-COR GHG files and support for multiple file types
- Integrated online help, videos and technical support from LI-COR
- Complete set of processing options, including frequency response correction, footprint estimation, random error estimation, and quality flagging
