EasyFlux™ PC 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.
EasyFlux™ DL is a free CRBasic program that enables a datalogger to report fully corrected fluxes of CO2, latent heat (H2O), sensible heat, and momentum from a Campbell Scientific open-path eddy-covariance (EC) system. Final fluxes are processed from raw high frequency time series data by applying commonly used corrections found in scientific literature.
The 27332 provides a recalibration with zero and span. When drift between zero and span checks seems unstable, or when diagnostic output indicates a problem, the instrument should be sent in for a full factory calibration with zero and span. An RMA is required.
The 27333 allows customers to send their EC155 or CPEC200 to Campbell Scientific and have Campbell Scientific perform a zero and span; an RMA (Returned Material Authorization) is required. The zero and span should be done when ambient conditions change significantly (i.e., seasonally).
