Plant Traits Help Explain the Tight Relationship between Vegetation Indices and Gross Primary Production

open access: yesRemote Sensing, 2020
Remotely-sensed Vegetation Indices (VIs) are often tightly correlated with terrestrial ecosystem CO2 uptake (Gross Primary Production or GPP). These correlations have been exploited to infer GPP at local to global scales and over half-hour to decadal ...

Retrieval of Leaf Area Index (LAI) and Soil Water Content (WC) Using Hyperspectral Remote Sensing under Controlled Glass House Conditions for Spring Barley and Sugar Beet [PDF]

open access: yes, 2010
Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or ...

Effects of Crop Leaf Angle on LAI-Sensitive Narrow-Band Vegetation Indices Derived from Imaging Spectroscopy

open access: yesApplied Sciences, 2018
Leaf area index (LAI) is an important biophysical variable for understanding the radiation use efficiency of field crops and their potential yield. On a large scale, LAI can be estimated with the help of imaging spectroscopy. However, recent studies have

Leaf area index (LAI) estimation based on vehicle-based laser scanning [PDF]

open access: yes2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
This paper proposes a novel approach for leaf area index (LAI) estimation based on vehicle-based laser scanning (VLS), which occurs as a state-of-the-art mapping technique. The method is advanced from the traditional terrestrial laser scanning (TLS), which has been primarily validated capable of predicting LAI.
