OPEC Open-Path Eddy-Covariance System
Using two or more cards is a fast and efficient method of
collecting data. Only new data is collected; however, two partial
files within a “baling” period are created. Variable file lengths
are not an issue with EdiRe. NOTE
Again, note that the first and last files (FIGURE 4-13) are smaller than the rest
of the files. The next time data is retrieved from the datalogger, the file
Ts_data_2000_02_25_0700.dat will be continued in another file (FIGURE
4-14).
