The high spatial and temporal variability of forest understorey light environments requires lengthy and/or extensive sampling in order to characterize...
Read morePhotocells were traversed at 6 canopy heights in a 15-yr-old plantation in North Carolina. When incident radiation was predominantly direct-beam, a bi...
Read moreA Calluna vulgaris canopy was reconstructed using 6-cm cuttings supported on a clear Perspex base drilled with randomly arranged holes of appropriate ...
Read moreAn instrument for measuring the distribution of irradiance in grass canopies is described; it demonstrated that light from an overcast sky was more un...
Read moreThe construction and calibration of a sensor for measuring light interception in crop canopies are described.
Read moreLight interception by a reconstructed canopy of Calluna vulgaris was recalculated on the basis of total skylight and equations developed to estimate i...
Read more[Cf. FA 35, 7073] A general theory is presented which describes the interaction between radiation and a Spruce forest. The canopy is divided into a se...
Read moreSpatial scale of processes is necessary information to design appropriate ecosystem research and management. In-stream ecological processes are tightl...
Read moreResults are compared of measuring radiation penetration coefficients using different types of sensor under clear and overcast conditions within a 20- ...
Read moreTotal solar, near infra-red, and photosynthetically active radiation were measured by tube solarimeters at Rothamsted in barley, sugar beet, field bea...
