Measurement of Oil Palm LAI by Manual and LAI-2000 Method*

Sampling methodology for LAI measurements with LAI-2000 in small forest stands

Leaf Area Index (LAI) plays a prominent role as an indicator of forest ecosystem condition in research on change detection. For this, rapid and reliable estimation of the effective LAI (LAIe) — this is the ratio of the total one-sided area of vegetation elements over the unit ground area) — at various scales is of utmost importance. We used the Licor LAI-2000 Plant Canopy Analyzer (PCA) for the...

Spatio-Temporal LAI Modelling by Integrating Climate and MODIS LAI Data in a Mesoscale Catchment

Vegetation is often represented by the leaf area index (LAI) in many ecological, hydrological and meteorological land surface models. However, the spatio-temporal dynamics of the vegetation are important to represent in these models. While the widely applied methods, such as the Canopy Structure Dynamic Model (CSDM) and the Double Logistic Model (DLM) are solely based on cumulative daily mean t...

Automated procedures for estimating LAI of Australian woodland ecosystems using digital imagery, Matlab programming and LAI / MODIS LAI relationship

Leaf area index (LAI) is one of the most important variables required for modelling growth and water use of forests. The implementation an approach to estimate LAI from digital pictures (LAID) has recently been advanced in Australia using digital image capture and gap analysis, which employs a novel methodology (Macfarlane et al 2006). This technique uses upward-looking wide-angle digital photo...

Inter-Comparison and Evaluation of the Global LAI Product (LAI3g) and the Regional LAI Product (GGRS-LAI) over the Area of Kazakhstan

Long-term global datasets of the Leaf Area Index (LAI) are important for monitoring global vegetation dynamics and are an important input for Earth system models (ESM). The comparison of long-term datasets is based on two recently available datasets both derived from AVHRR (Advanced Very High Resolution Radiometer) time series. The LAI3g dataset is developed from the new improved third generati...
