Flux Calculator version 2 (FC2)
The GUI software calculates turbulent statistics including mean, fluxes, QC/QA information, footprint, and high-order moment with the eddy covariance method. The software supports necessary corrections including high-frequency loss correction, coordinate rotation, density fluctuation correction. The software is developed by Visual C++ 6.0.

Flux Analysis Tool version 2.0 (FAT2)
The GUI software provides flux partitioning of NEE, and gap-filling based on the non-linear regression, look-up-table, and mean diurnal variations methods with bootstrapping. The software also provides determination of friction velocity threshold, quality control of fluxes by the median absolute deviation method, and possible magnitudes of spurious correlation among GPP and RE. The software is developed by Visual C++ 6.0.

iBLM-EC 2.0
The CUI software provides inverse estimates of ecophysiological parameters (e.g., maximum carboxylation, stomatal conductance behavior, and aerodynamic conductance) based on continuous observations of the eddy covariance fluxes and meteorology. The ecophysiological parameters are inferred with a combination of the biochemical photosynthesis model, stomatal conductance model, sun/shade radiation transfer model, and bulk transfer model. The software is developed by Visual Studio C++ 6.0, but can be easily compiled using other C++ compilers.
