As a summary, the steps of the calibration and the data processing are as follows:
1. determination of the lag times
2. synchronization of the computers
3. calculation of the calibration functions
4. averaging time determination
5. conversion of voltage signal into physical quantities
6. wind vector rotation
7. trend removal
8. data screening
9. calculation of covariances
10. conversion into physical fluxes
11. instationarity test
12. spectral corrections
This is a routine method which is suggested to be used by other investigators
who conduct long term, tower based eddy covariance measurements with similar
instrumentation.
