Computer simulation modeling of Leaf Area Index (LAI) in maize
Acta Agraria Debreceniensis, 2014 This study presents a PHP-based model capable of calculating maize leaf area index. The model calculates LAI from emergence to 75% silking. The basis of calculation is represented by the daily average temperature values. The usability of the model was tested using three years' temperature and LAI data series from the values obtained by the weather ...

Leaf area index (LAI) map of a protected area within the caldera of Vico Lake (Italy)
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2003 ABSTRACT Structural traits of the vegetation types and plantations occurring in a protected area within the caldera of Vico Lake (Italy) were analysed. There were significant correlations among structural traits, at leaf and stand level. Leaf area index (LAI) and specific leaf area (SLA) were the most significantly correlated traits. LAI rose according

The Limitations and Robustness of Data Assimilation in Terrestrial Ecosystem Modelling. [PDF]
, 2013 Accurately estimating how much carbon is leaving the atmosphere and being taken up by plants, by processes such as photosynthesis, is critical in order to make accurate climate forecasts. There is a large uncertainty of this atmosphere-plant carbon flux,

Aerial high-throughput phenotyping of peanut leaf area index and lateral growth
Scientific Reports, 2021 Leaf area index (LAI) is the ratio of the total one-sided leaf area to the ground area, whereas lateral growth (LG) is the measure of canopy expansion. They are indicators for light capture, plant growth, and yield.

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

Leaf area index estimation using top-of-canopy airborne RGB images
International Journal of Applied Earth Observations and Geoinformation, 2021 Leaf Area Index (LAI) is one of the most important biophysical properties of a crop, used in detecting long-term water stress, estimating biomass, and identifying crop growth stage.

Leaf area index (LAI) and gap fraction. A discussion
Baltic Forestry, 2023 Methodological aspects of estimating leaf area from gap fraction measurements are discussed. Instead of the common practice of linking in the Beer-Lambert law leaf area index and clumping factor together, the clumping factor and Ross-Nilson geometry function as two structure parameters should be combined into the effective geometry function, which ...
