The general overview of the flux processing chain has been updated here: For the general processing steps: Flux Processing Chain For data sharing within FLUXNET: FLUXNET Requirements
In case you ever wondered how our raw data files look like and what is needed before we can use them in EddyPro for flux calculations (and what does “compressed” vs “uncompressed” mean), here is a new Article for you: Eddy Covariance Raw Data Binary Files
Fluxes are calculated automatically every day. Here is a new article with more details: Automatic Fluxes
In case you ever wanted to know more about how calculations are automated, you can find a new article here: Automation Schedule
The VPC (virtual PC) now runs with 8 virtual processors (Intel Xeon E5-2650 v4 @2.2GHz) and 32GB RAM. This will be helpful in running automatic fux calculations, QuickView plot generation and data conversions in parallel. For more info about the VPC, please see here.
The north off-set of the sonic anemometer (the direction in which the sonic anemometer north arrow points) in CH-DAV is 270.28°. It was determined via this map: Source: geo.admin.ch

There will be a lot of different sites measured in the InnoFarm project. To keep an overview for flux calculations, the EC raw binary format for CH-INO is now documented here: EC Raw Binary Format (CH-INO)
The ICOS DataFlow from CH-DAV to the ETH grassland server is now active. Filenames and variable names will soon be changed to their final ICOS file- & variable names. More info here: Dataflow Exception: at the moment 90_images_10_webcam files are transfered directly from the LANNER to the ETH grassland server.
