EasyFlux®-PC (PC for personal computer) is a free computer program that processes high-frequency time-series data, collected using a Campbell Scientific eddy-covariance flux system, into fluxes following community-accepted practices. Fully corrected fluxes of CO2, latent heat (H2O), sensible heat, and momentum are available, in generic, AmeriFlux, and GHG-Europe ASCII formats.

Ventajas y características

  • Intuitive and easy to use; begin processing data in under a minute
  • Uses community-tested and -reviewed, open-source software
  • Supports native Campbell Scientific TOB1 file format collected from an open-path eddy-covariance system (IRGASON or EC150 with CSAT3)
  • Available at no charge


Descripción técnica

Provides fully corrected outputs of CO2 flux, latent heat flux, and sensible heat flux at a user-defined interval (e.g., 30 minutes). Also provides many other variables of atmospheric properties, instrument diagnostics, and intermediate corrections.

Default processing:

  • Despike and filter data using sonic anemometer and gas analyzer diagnostic codes, signal strengths, and measurements output range threshold
  • Apply coordinate rotation with an option to use the double rotation method (Tanner and Thurtell, 1969) or planar fit method (Wilczak et al., 2001)
  • Lag CO2 and H2O measurement against sonic wind measurement for maximization of CO2 and H2O flux (Horst and Lenschow, 2009; Foken et al., 2012)
  • Apply low-frequency correction following Moncrieff et al., 2004
  • Apply high-frequency corrections following Moncrieff et al. (1997), Massman (2000, 2001), or Horst (1997)
  • Correct sonic temperature for the effect of humidity following van Dijk et al., 2004
  • Apply correction for air density fluctuation using Webb et al., 1980
  • QA/QC data quality checks following Foken (2003)


Required Equipment

  • CR6, CR3000, or CR1000 datalogger
  • IRGASON or EC150 with CSAT3A
