✦ Synopsis

other two. Considering that radiation fog has the smallest particlesize distribution, our results should stand for this type of fog as well. Although we do not know the exact particle-size distribution of the fog in the measured link, the upslope fog is similar in formation to the advection fog; therefore, we also believe that, for this type of fog, the performance of the far-IR link should not be worse than those of the other two. Of course, present-day commercial technology still benefits shorter wavelengths, mostly due to the availability of low-cost sources and detectors. However, new technologies can produce competing devices for the far-IR window; thus our results demonstrate that it is worth working in the development of appropriate devices and systems because the optical channel indeed performs better at long wavelengths in most cases.
