Biotic controls over spectral reflectance of arctic tundra vegetation
2005
International Journal of Remote Sensing
In this study, seasonal field measurements of the normalized difference vegetation index (NDVI), using a field spectroradiometer, and leaf area index (LAI), using a LI-COR LAI-2000 Plant Canopy Analyzer, were compared with above-ground phytomass data to investigate relationships between vegetation properties and spectral indices for four distinct tundra vegetation types at Ivotuk, Alaska (68.49u N, 155.74u W). NDVI, LAI and above-ground phytomass data were collected biweekly from four 100 m6100
