Analysis of Nutrient-Specific Response of Maize Hybrids in Relation to Leaf Area Index (LAI) and Remote Sensing [PDF]
Plants, 2022 Leaf area index (LAI) indicates the leaf area per ground surface area occupied by a crop. Various methods are used to measure LAI, which is unitless and varies according to species and environmental conditions.

Comparison of EPIC-Simulated and MODIS-Derived Leaf Area Index (LAI) across Multiple Spatial Scales. [PDF]
Remote Sens (Basel), 2020 Modeled leaf area index (LAI) in conjunction with satellite-derived LAI data streams may be used to support various regional and local scale air quality models for retrospective and future meteorological assessments. The Environmental Policy Integrated Climate (EPIC) model holds promise for providing LAI within a dynamic range for input into climate ...

Sentinel Image to Estimate Industrial Tomato Leaf Area Index
Brazilian Archives of Biology and Technology, 2023 The Leaf Area Index (LAI) is one of the main physiological parameters of the plant related to transpiration, productivity and rainfall interception. Among the methods to determine the LAI, the use of remote sensing that estimates the LAI through image ...

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 ...

Delete---ICESat-2 leaf area index (LAI) Retrieval Comparisons
, 2021 This is the first release of the LAI used for the submitted paper: Guo et al., 2021: Exploring photon-counting laser altimeter ICESat-2 in retrieving LAI and correcting clumping effect. The grid LAI derived from airborne LiDAR data was used to validate the LAI derived from ICESat-2, which has been validated by the field measurements and has the spatial
