Using the LAI-2200 in Sunny Conditions
Monday, November 1st, 2010
In a previous tech tip, we used digital photography to show how canopy gap fraction measurements can be over-estimated if measurements are taken when foliage is brightly lit (i.e. when measurements are taken in direct sunlight). The over-estimation of gap fraction leads to under-estimation of leaf area index (LAI), typically by about 10% or more….

Appropriate Sky Conditions for Using the LAI-2000
Tuesday, May 6th, 2008
For users of the LAI-2000 Plant Canopy Analyzers, just a reminder that an overcast sky is the best condition in which to use the instrument. Under cloudy skies, the contribution of scattered radiation is low; when the direct beam of the sun is shining on foliage, scattered radiation is significantly increased. The LAI-2000 optical sensor…
