Short summary
Laboratory and field experiments were carried out in order to define suitable configuration ranges for the gas sampling systems of infrared gas analyzers used in eddy covariance measurements. They show that filters may have a strong impact on the pressure drop in the GSS but no significant impact on cut-off frequency. Conversely, the rain cup design was found to be the main limiting factor of cut-off frequency in the field. Its impact on pressure drop was also found to be noteworthy.
