Inferring Amazon leaf demography from satellite observations of leaf area index [PDF]

open access: yesBiogeosciences, 2012
Seasonal and year-to-year variations in leaf cover imprint significant spatial and temporal variability on biogeochemical cycles, and affect land-surface properties related to climate.

Estimating Leaf Area Index with Dynamic Leaf Optical Properties [PDF]

open access: yesRemote Sensing, 2021
Leaf area index (LAI) plays an important role in models of climate, hydrology, and ecosystem productivity. The physical model-based inversion method is a practical approach for large-scale LAI inversion.

LEAF AREA INDEX RETRIEVED FROM THERMAL HYPERSPECTRAL DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Leaf area index (LAI) is an important essential biodiversity variable due to its role in many terrestrial ecosystem processes such as evapotranspiration, energy balance, and gas exchanges as well as plant growth potential. A novel approach presented here

Estimation of Leaf Area Index across Biomes and Growth Stages Combining Multiple Vegetation Indices [PDF]

open access: yesSensors
The leaf area index (LAI) is a key indicator of vegetation canopy structure and growth status, crucial for global ecological environment research. The Moderate Resolution Spectral Imager-II (MERSI-II) aboard Fengyun-3D (FY-3D) covers the globe twice ...

Is stunting in children under five associated with the state of vegetation in the Democratic Republic of the Congo? Secondary analysis of Demographic Health Survey data and the satellite-derived leaf area index [PDF]

open access: yesHeliyon, 2023
Background: The prevalence of stunting in the Democratic Republic of the Congo (DRC) is one of the highest globally. However, only a few studies have attempted to measure the association between stunting and vegetation, which is an important food source.

Leaf area index in a forested mountain catchment

open access: yesHungarian Geographical Bulletin, 2018
Leaf area index (LAI) belongs among the catchment characteristics widely used in hydrological models but still associated with great uncertainties. In a mountain forest catchment, the leaf area affects retention and evapotranspiration loss, and it could ...

Usage of Lidar Data for Leaf Area Index Estimation

open access: yesGeoScience Engineering, 2014
Leaf area index (LAI) can be measured either directly, using destructive methods, or indirectly using optical methods that are based on the tight relationship between LAI and canopy light transmittance.
