A detailed study of rainfall passage and capture in the tree canopy
The forest canopy breaks up and captures rainfall, playing an important role in many hydrological, biogeochemical and ecological processes. Over the course of a year Forest Research collected detailed metereological and precipitation data and characterised the canopy at two sites: an oak forest at Alice Holt and a Scots pine forest at Thetford. The team evaluated the suitability of Gash’s model – the most widely used model of canopy interception – to the short timescales required by modern ecosystem process models.
