Configuring Eddy Covariance Measurements
The
Site Setup
window is where you configure most of the eddy covariance system
settings. The information entered here will comprise the metadata file, which
describes the system setup. The addition of the metadata file inside the .ghg file
allows you to:
l
Avoid duplicate retrieving and re-typing of information needed for processing
the file from any external data source;
l
Easily store raw data for future reprocessing;
l
Account for dynamic site parameters that change over the course of the data col-
lection period (e.g., the canopy height of a crop);
l
To a large extent, simultaneously process files acquired with different setups.
IMPORTANT: The SmartFlux System or SmartFlux 2 System will not compute
flux results if metadata are not entered properly.
The metadata file is used by EddyPro
®
. All information in the metadata file is
stored as plain text and can be retrieved and edited at any time.
Eddy Covariance Checklist
Table 3-2 on the facing page is a checklist of settings that either must be set or that
we recommend setting before recording datasets that can be processed by the
SmartFlux System, SmartFlux 2 System, or EddyPro
®
Software. Review this check-
list to be sure that everything is set properly.
