Abstract
Directional reflectance measurements were made over a semi-desert gramma (Bouteloua spp.) grassland at various times of the growing season. View angle measurements from +40° to -40° were made at various solar zenith angles and soil moisture conditions. The sensitivity of the normalized difference vegetation index (NDVI) and the soil-adjusted vegetation index (SAVI) to bidirectional measurements was assessed for purposes of improving remote temporal monitoring of vegetation dynamics. -from Authors
