Method P.192 left column 3rd paragraph: "In this paper [investigators] present a literature review, database and synthesis of 1008 LAI measurements collected from 15 global biomes. This paper serves as an extension to a technical report developed by us for the Oak Ridge National Laboratory (Scurlock et al., 2001), with additional analyses pertinent to ecological and remote sensing applications of the database."
Comments P.191 left column 3rd paragraph: "Biomes with LAI values well represented in the literature included croplands, forests and plantations. Biomes not well represented were deserts, shrublands, tundra and wetlands. Nearly 40% of the records in the database were published in the past 10 years (1991–2000), with a further 20% collected between 1981 and 1990. Mean (± SD) LAI, distributed between 15 biome classes, ranged from 1.3 ± 0.9 for deserts to 8.7 ± 4.3 for tree plantations, with temperate evergreen forests (needleleaf and broadleaf) displaying the highest average LAI (5.1–6.7) among the natural terrestrial vegetation classes."
