OPEC Open-Path Eddy-Covariance System
4.1.4 File Management with CardConvert
CardConvert is a utility that is shipped with LoggerNet and is used to convert
the files on a card from the compact file format TOB3 to a TOB1, TOA5, or
Array Compatible CSV (see FIGURE 4-7). This utility is installed on the PC
under the Start menu in the Programs | Campbell Scientific | LoggerNet |
Utilities group. To take advantage of all the functionality described in this
section, use CardConvert version 1.2 or later.
Copy the data from the PC/CF card onto the computer using Windows
Explorer. Place the file in a temporary working directory, e.g., C:\Temporary.
It will take about 15 minutes to copy a 1024 Mbyte file (about 28 days of
10 Hz time series from a Basic Open-Path Eddy-Covariance system).
It is good practice to archive the raw data as copied from the
PC/CF card. Use a zip utility to compress the file, before
archiving it to a CD. Compressing a 1024 Mbyte time series file
will take about 2 minutes using the built-in Windows XP zip
utility. TIP
