Measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant survival were collected along with these vegetation data to test a model to estimate CWI as a function of fog-water movement and these vegetation characteristics.

The outputs of two versions of the Single-Layer Wet Canopy Water Balance model. Parameters include cloud water interception, evaporation of rainwater or fog water from wet canopy (interception evaporation), and canopy water storage.

Cloud-water interception (CWI) is the process by which fog or cloud water droplets are captured and accumulate on the leaves and branches of plants, some of which drips to the ground. Prior studies in Hawai'i indicate that CWI is highly variable and can contribute substantially to total precipitation. In this study, we monitored CWI and other processes at five mountain field sites on the Islands of Oʻahu, Maui, and Hawaiʻi to explore how CWI (1) varies with different climate and vegetation characteristics, (2) affects plant water use and growth, and (3) contributes to water resources. Results show that annual CWI varied from 158 to 910 mm, accounting for 3-34% of total water input at individual sites. This large...

Measurements of fog, fog interception parameters, and climate variables such as wind, radiation, temperature, and humidity, along with vegetation data, to test a model to estimate CWI as a function of fog-water movement and vegetation characteristics.
The U.S. Geological Survey Pacific Islands Water Science Center and the University of Hawaii at Manoa Department of Geography, in cooperation with the U.S. Department of Interior Pacific Islands Climate Adaptation Science Center initiated a field data-collection program as part of a study to quantify the impacts of drought on water resources and the importance of cloud-water interception in mitigating the impacts of drought (see Related External Resources link below). The goal of the data-collection program is to provide information for evaluating the role that cloud-water interception in Hawaii’s rain forests has in providing moisture for plants, reducing wildfire risk within the fog zone, and contributing to groundwater...
