Biotic controls over spectral reflectance of arctic tundra vegetation / S.M. Riedel, H.E. Epstein, D.A. Walker.

Title: Biotic controls over spectral reflectance of arctic tundra vegetation / S.M. Riedel, H.E. Epstein, D.A. Walker.
Author(s): Riedel, S. M.
Epstein, H. E.
Walker, D. A.
Date: 2005.
In: International Journal of Remote Sensing. (2005.), Vol. 26(11) (2005)
Abstract: Seasonal field measurements of 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 (68.49°N, 155.74°W) during the 1999 growing season. Study shows NDVI is useful for estimating levels of total live above-ground phytomass and LAI in tundra vegetation. Shrub phytomass controls NDVI across all vegetation types. LAI showed strongest relationship with overstorey component (total above-ground excluding moss and lichen) of phytomass and also showed significant relationship with NDVI.
