Short summary
The vortex intake significantly reduced maintenance requirements and downtime for a closed-path eddy-covariance system compared to the original inline filter design. Vortex intake kept the sample cell windows cleaner, preserving the optical signal strength of CO2 longer. Its installation also avoided the need for an inline filter in the sample path, sustaining an acceptable sample cell differential pressure over a much longer period. There was no significant attenuation of high frequencies.
