Abstract A novel and inexpensive instrument to monitor solar radiation interception at up to 32 locations simultaneously is described. It employs small-area, lightweight sensors that are leaf-mountable and have very good spectral and angular responses. A portable computer readily controls fast data acquisition and in-field processing to histograms, which are the most general irradiance measures to relate to nonlinear plant responses such as photosynthesis. Two field tests verified the instrument's reliability and operational convenience, and also directly compared radiation interception at space-fixed locations vs. nearby leaves. A number of new physiological and canopy-model tests that the instrument makes possible are described. The monitor is constructed from standard electronic components and may be readily modified for many expanded capabilities.
AbstractList A novel and inexpensive instrument to monitor solar radiation interception at as many as 32 locations simultaneously is described. It uses small-area, lightweight sensors that are leaf-mountable and have good spectral and angular responses. A portable computer readily controls fast data acquisition and in-field processing to histograms, which are the most general irradiance measures to relate to nonlinear plant responses such as photosynthesis. Two field tests verified the instrument's reliability and operational convenience and, also, directly compared radiation interception at space-fixed locations vs. nearby leaves. A number of new physiological and canopy-model tests that the instrument makes possible are described. The monitor is constructed from standard electronic components and can be readily modified for many expanded capabilities.
