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