Frequently Asked Questions
Q What do I need to make basic eddy covariance measurements?
Q Are there restrictions on where I can use the eddy covariance method?
Q What sonic anemometers can I use with LI-COR gas analyzers?
Q Why do we need coordinate rotation in eddy covariance data processing?
Q Why do we consider the Webb-Pearman-Leuning (WPL) term in eddy covariance data processing?
Q What is the Webb-Pearman-Leuning (WPL) term for Eddy Covariance flux? Do I need it?
Q Do I need to measure the water vapor concentrations when measuring CO2 concentrations and computing eddy covariance CO2 flux with data from closed path analyzers, such as the LI-6251, LI-6252, LI-6262, or LI-7000?
Q I see that you offer both closed path and open path CO2/H2O analyzers for eddy covariance measurements. Which is more appropriate for me?
Q How important is signal synchronization when collecting high frequency data for eddy covariance measurements?
Q I know what I want my output frequency rate to be, but what should I set the bandwidth to?
