Regional‐Scale Relationships of Leaf Area Index to Specific Leaf Area and Leaf Nitrogen Content [PDF]
Ecological Applications, 1994 Specific leaf area (SLA) is an important link between vegetation water and carbon cycles because it describes the allocation of leaf biomass per unit of leaf area. Several studies in many vegetation types have shown that canopy SLA is closely related to canopy leaf nitrogen (N) content and photosynthetic capacity.

Validation and application of the MERIS Terrestrial Chlorophyll Index. [PDF]
Climate is one of the key variables driving ecosystems at local to global scales. How and to what extent vegetation responds to climate variability is a challenging topic for global change analysis.

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2020 The leaf area index (LAI) is one of the most common leaf area and canopy structure quantifiers. Direct LAI measurement and determination of canopy characteristics in larger areas is unrealistic due to the large number of measurements required to create ...

Leaf area index of potato crop under three nitrogen fertilization treatments
Agronomía Colombiana, 2017 Nitrogen fertilization has considerable effects on growth and yield of the potato crop. Additionally, leaf expansion is one of the most important growth parameters that can be used to optimize the management of agroecological resources.

Mapping Leaf Area Index With a Smartphone and Gaussian Processes [PDF]
IEEE Geoscience and Remote Sensing Letters, 2015 Leaf area index (LAI) is a key biophysical parameter used to determine foliage cover and crop growth in environmental studies. Smartphones are nowadays ubiquitous sensor devices with high computational power, moderate cost, and high-quality sensors. A smartphone app, called PocketLAI, was recently presented and tested for acquiring ground LAI estimates.

LEAF AREA INDEX RETRIEVED FROM THERMAL HYPERSPECTRAL DATA [PDF]
The 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
