The LaiPen LP 110 measures leaf area index (LAI), defined as the one-sided green leaf area per unit area of ground surface (m2 per m2) in broadleaf tree canopies. The LaiPen LP 110 calculates LAI and other canopy structure attributes from solar radiation measurements made with a wide-angle optical sensor. Measurements made above and below the canopy are used to determine canopy light interception at five angles, from which LAI is calculated using a radiative transfer model in plant canopies.
The LaiPen LP 110 can operate in two operating modes:
Single-sensor mode: the reference measurement is taken before, after or during the measurement with the same instrument;
Two-sensor mode: a second instrument is used for automatic recording of the reference signal.
