| Zusammenfassung |
| Accurate rainfall measurements are crucial for water resource and environmental
assessments but can be difficult to achieve in extensive areas of forest. This paper
reviews the different techniques for measuring rainfall to a forest area and presents the
results of a 5-year experiment comparing the catches of gauges installed above a forest
canopy with those of ground level gauges outside the forest. It examines the consistency
of the catches between the canopy gauges, the sensitivity of the catch to the height of
the gauge rim above the forest canopy, and compares the canopy gauge catches to the ‘true’
rainfall in ground level gauges just outside the forest. The study shows that suitably
designed and maintained canopy gauges can provide consistent measures of rainfall to a
forest surface that are sufficiently accurate for most purposes and offer a preferable
alternative to measurements in small clearings.
