The LI-7700 is the only open path instrument suitable for field measurements of CH4 Eddy Covariance. Open path instruments offer several advantages, including in situ measurement of signal without any alteration, minimized signal attenuation, and low power consumption. The exposed optical path, however, has its own set of challenges, including signal decay as a result of the deposition of foreign objects in the optical path and on the associated optical components. These may include dust, dirt, debris, pollen, salt spray,…
