WebJun 15, 2024 · Published SIF values vary beyond what might be expected from differences in species, season, or location. It is likely that the SIF instrumentation variability across the literature explains the lack of a strong relationship between mean SIF and mean GPP values at the tower scale. WebThe PFD of the SIF is the sum of the PFD values of all of the components in the SIF (i.e., logic solver, final control element, and sensor). Therefore, to design a SIF for a target SIL, you need to determine the PFD of each component in the SIF (as discussed later) and choose components whose overall PFD is within the range given in Table 1.
