Ceptometers are ground-based radiation sensors that measure photosynthetically active radiation (PAR) in plant canopies. They make PAR measurements both above and below the canopy to calculate the leaf area index (LAI). Ceptometers are used in vegetation and agricultural research on plant growth, canopy structure, light interception, and other canopy characteristics.
