Leaf area index (LAI), the ratio of leaf surface area to ground surface area, is a key variable when studying or comparing plant biomass.  An accurate and non-destructive method for measuring LAI is the LAI-2200C Plant Canopy Analyzer, which measures light transmission through the canopy and uses an inverted gap fraction technique to calculate LAI.  With the inclusion of a new light scattering correction, this instrument consistently outperforms other methods in a variety of canopy types and sky conditions.
