Abstract
Fog drip is an important parameter in the water balance of montane forest ecosystems on Mauna Loa (summit elevation 4170 m). In the present study relative fog interception was sampled on the windward slope of Mauna Loa, along an altitudinal transect from 600 to 3400 m. Stations were instrumented with louvered aluminum screen fog interceptors, paired to standard rain gages. The analysis of weekly rain and fog data over an 11 month period exposed the substantial contribution of fog in the mid-mountain belt between 1500 and 2500 m, particularly during the summer months with low direct rainfall. A set of simple regression equations were derived to predict fog interception as a function of rainfall and elevation.
