Re-Assessing the Measurement of Fogwater Inputs to a Tropical Ecosystem

For several years the hydrological importance of the fogand cloudwater deposition to ecosystems in the tropics has been of great interest. In earlier studies carried out in the humid tropics the amount of deposited cloudwater was estimated by indirect methods based on the physical characteristics of the utilized cloudwater collector (1, 2) or on the comparison of the amounts of net and gross precipitation for events with and without fog. The basic equation of this approach, which is also refered as ’water mass balance approach’ is
