What is OpenFlux EC Platform?

An open-source data processing software for eddy covariance flux observations, rigorously cross validated with the industry reference tool EddyPro to ensure comparability and reliability of computational results.

Early Access

Platform Features

Real time computing architecture
• Support edge computing devices to automatically perform flux calculation in a 30 minute cycle
• Once the original high-frequency data file is closed, it enters the processing flow without waiting for the experiment to end
Multi component joint processing
• Support CO₂、CH₄、NH₃、N₂O、H₂O and other multi-component synchronous flux output
• When multiple analyzers are combined, the time delay and frequency loss of each gas channel need toIndependent correctionPost unified covariance calculation
Engineering Configuration
• A graphical wizard guides the generation of parameter configuration files, reducing the threshold for manual editing
• The output format is compatible with FLUXNET/ICOS, making it easy for subsequent data organization and platform integration
Parameterized correction framework
• Spectral correction approach for instrument configuration: optical path length, response function, electronic delay, sensor spacing
• Calculate the model to match the real physical characteristics of the instrument
• Non standard instruments can also obtain accurate resultsHigh precision flux
