Experimentally measured average mass and frequency of the single falling droplet from each test surface during 90 minutes in (a) fog harvesting and (b) dew harvesting. As the surface has the better water removal characteristics, the average droplet mass gets smaller. (c) Mass ratio and frequency ratio between fog and dew harvesting. While the average mass is similar within about 10% difference under the two test conditions, the falling frequency strongly depends on the harvesting environment for non-wettable surfaces.
