Climate-related vegetation characteristics derived from Moderate Resolution Imaging Spectroradiometer (MODIS) leaf area index and normalized difference vegetation index
[1] MODIS-based leaf area index (LAI) and normalized difference vegetation index (NDVI) are used to examine detailed information regarding actual growing season and total annual production for various regions. Overall, MODIS LAI has larger variability and demonstrates more information regarding the evolution and structure of the seasonal vegetation characteristics. In contrast, the NDVI saturat...
متن کاملMapping and Attributing Normalized Difference Vegetation Index Trends for Nepal
Global change affects vegetation cover and processes through multiple pathways. Long 1 time series of surface land surface properties derived from satellite remote sensing give unique 2 abilities to observe these changes, particularly in areas with complex topography and limited research 3 infrastructure. Here, we focus on Nepal, a biodiversity hotspot where vegetation productivity is 4 limited...

متن کاملAvhrr Compatible Vegetation Index Derived from Meris Data
The AVHRR compatible vegetation index derived from MERIS full resolution (FR) data is based on top of atmosphere radiances (ESA L2 data). This continuity index is developed using radiative transfer models for simulating the reflectance of the broad spectral channels of the NOAA – AVHRR and the small spectral bands of MERIS. A linear combination of MERIS channels describes each AVHRR channel. Th...
متن کاملEstimation of vegetation clumping index using MODIS BRDF data
The foliage clumping index quantifies the degree of the deviation of leaf spatial distribution in the canopy from the random case. It is of comparable importance for ecological models as the leaf area index for quantifying radiation interception and distribution in plant canopies. Previously, an improved angular index named normalized difference between hotspot and darkspot was proposed for ret...
