| Zusammenfassung |
| Analysing Eddy-Covariance measurements involves extensive processing, which puts
technical labour to researchers. There is a need to overcome difficulties in data
processing associated with deploying, adapting and using existing software and online
tools.
We tackled that need by developing the REddyProc package in the open source
cross-platform language R that provides standard processing routines for
reading half-hourly files from different formats, including from the recently
released FLUXNET 2015 dataset,
uStar threshold estimation and associated uncertainty,
gap-filling,
flux partitioning (both night-time or daytime based), and
visualization of results.
Although different in some features, the package mimics the online tool that has been
extensively used by many users and site Principal Investigators (PIs) in the last years, and
available on the website of the Max Planck Institute for Biogeochemistry. Generally,
REddyProc results are statistically equal to results based on the state-of the art tools. The
provided routines can be easily installed, configured, used, and integrated with
further analysis. Hence the eddy covariance community will benefit from using the
provided package allowing easier integration of standard processing with extended
analysis. This complements activities by AmeriFlux, ICOS, NEON, and other regional
networks for developing codes for standardized data processing of multiple sites in
FLUXNET. |
