LI-COR LI7200RS, Instruction Manual

This—and subsequent versions of EddyPro—provide the capability to export a
SmartFlux configuration file, that can then be uploaded via the gas analyzer PC soft-
ware. Complete documentation is provided in the EddyPro help.
There are additional considerations if you use
EddyPro Advanced
in the SmartFlux
or SmartFlux 2 System. For many scenarios, you will simply need to configure the
advanced settings as you see fit, and load the SmartFlux configuration file into the
SmartFlux or SmartFlux 2 System following the instructions provided below.
However, if you wish to use a
Planar-fit method for Axis Rotation
, the
Automatic
Time Lag Optimization
option, or one of the
in situ spectral correction
methods
(Horst, 1997; Ibrom et al., 2007), you will need to process an existing data set from the
site in order to configure the parameters for these settings .
Important: In order for the parameters to be valid, the site must not have under-
gone any significant changes between the time when the existing data set was
collected and when the SmartFlux or SmartFlux 2 System is deployed. The instru-
ment configuration should remain unchanged during the sampling period if the
settings are to apply to the SmartFlux configuration file as well. For closed-path
systems, the dataset used to optimize time lags and for the spectral assessment
must refer to a period in which the sampling line did not undergo major modi-
fications, such as replacement of tube or filters, change of the flow rate, etc.
When you create the configuration file, only the controls that can be configured for
the SmartFlux or SmartFlux 2 System are enabled, and the other controls are dis-
abled.
