OPEC Open-Path Eddy-Covariance System
To enable LoggerNet’s data collection, click on the Status Monitor button in
the Toolbar. Select the station and click on the “Toggle On/Off” button. The
time of the next data collection will appear in the “Next Data Call” column (see
FIGURE 4-4). To display additional station information, right click on any
column header and then Select “Column…”. For more information, see
Section 6.1 Status in the LoggerNet manual.

4.1.2 File Management with Baler
The data is collected by LoggerNet and placed in the LoggerNet cache. Two
instances of the Baler, one for the time series data and the other for the flux
data, will pull the data from the cache and “bale” it into a user specified file
size (see FIGURE 4-5 and FIGURE 4-6). Campbell Scientific recommends
using a one hour bale size for time series data that will be post processed by
EdiRe and a 1 day bale size for the flux data. To run more than one instance of
the Baler, use the “/WorkDir=pathname” switch and two shortcuts, one for the
time series data and the other for the flux data (see Section 6.5 in the Baler
manual).
While the system is set up in the lab or outside near the lab,
practice not only operating the system and data collection, but
also file management and data processing. Only through this
type of experimentation will you determine the file sizes and
procedures that work best for you. TIP
