Estimation of leaf area index and plant area index of a submerged macrophyte canopy using digital photography. [PDF]

open access: yesPLoS ONE, 2012
Non-destructive estimation using digital cameras is a common approach for estimating leaf area index (LAI) of terrestrial vegetation. However, no attempt has been made so far to develop non-destructive approaches to LAI estimation for aquatic vegetation.

Stage 1 Validation of Plant Area Index From the Global Ecosystem Dynamics Investigation [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2023
The Global Ecosystem Dynamics Investigation (GEDI) aims to provide improved characterization of forest structure, and plant area index (PAI) is one of many variables provided in the official GEDI Level 2B (L2B) product suite. However, since release, few quantitative validation studies have been conducted.

Modelling Plant Responses to Elevated CO2: How Important is Leaf Area Index? [PDF]

open access: yesAnnals of Botany, 2004
The problem of increasing CO(2) concentration [CO(2)] and associated climate change has generated much interest in modelling effects of [CO(2)] on plants. While variation in growth and productivity is closely related to the amount of intercepted radiation, largely determined by leaf area index (LAI), effects of elevated [CO(2)] on growth are primarily ...

Simulation of Planted Area Index (PAI) for Crop Spacing Methods in Plant Factory [PDF]

open access: yesJournal of Biosystems Engineering, 2011
Various crop spacing methods have been implemented so far for the greenhouse and plant factory applications. However, there is no generally accepted parameter for evaluation of plant spacing efficiency in plant production system. In this study, `Planted Area Index` (PAI) of a spacing method is defined as the ratio of the planted area in the field to ...

Comparison of in Situ Plant Area Index and Remotely Sensed Leaf Area Index of Northeastern American Deciduous, Mixed, and Coniferous Forests for SMAPVEX19-22

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Leaf area index (LAI) and plant area index (PAI) are critical biophysical parameters for quantifying foliage density of crops and trees. As such they may also be effective metrics to estimate the impact of leafy vegetation on microwave signals, such as ...

CoverPy: Automated estimates of plant area index, vegetation cover, crown cover, crown porosity, and uncertainties from digital cover photography in Python

open access: yesSoftwareX
Implemented in Python, CoverPy enables automated estimation of plant area index (PAI), the fraction of vegetation cover (FCOVER), crown cover (CC), and crown porosity (CP) from digital cover photography (DCP).

Sustainability Index of Solar Power Plants in Remote Areas in Indonesia [PDF]

open access: yesTechnology and Economics of Smart Grids and Sustainable Energy, 2021
Energy is an inseparable component in human life in every aspect. However, many regions cannot utilize energy sources to support their daily activities, so there are several breakthroughs made by the government, including the construction of solar power plants in remote areas.
