Estimation of forest leaf area index using vegetation indices derived from Hyperion hyperspectral data
Field spectrometer data and leaf area index (LAI) measurements were collected on the same day as the Earth Observing 1 satellite overpass for a study site in the Patagonia region of Argentina. We first simulated the total at-sensor radiances using MODTRAN 4 for atmospheric correction. Then ground spectroradiometric measurements were used to improve the retrieved reflectance for each pixel on th...
متن کاملSpectral compatibility of vegetation indices across sensors: band decomposition analysis with Hyperion data
Vegetation indices (VIs) are widely used in long-term measurement studies of vegetation changes, including seasonal vegetation activity and interannual vegetation-climate interactions. There is much interest in developing cross-sensor/multi-mission vegetation products that can be extended to future sensors while maintaining continuity with present and past sensors. In this study we investigated...
متن کاملFull Polarimetric Emissivity of Vegetation-Covered Soils: Vegetation Structure Effects
In May 1999 the SMOS Earth Explorer Opportunity mission was selected by ESA to provide global soil moisture and sea salinity maps using the MIRAS L-band aperture synthesis interferometric radiometer. At this frequency there is a high dynamic range of the soil moisture signature and surface roughness effects are small, as well as vegetation effects. However, they cannot be neglected at large obs...
متن کاملVegetation and soil lines in visible spectral space: a concept and technique for remote estimation of vegetation fraction
The goal of this study is to investigate the information content of re ectance spectra of crops in the visible and near infrared range of the spectrum and develop a technique for remote estimation of vegetation fraction (VF). For four wheat species with VF=100% in a wide range of pigment contents and compositions, a high degree of covariance was found for paired re ectances (R) at 550 nm vers...
متن کاملClimate-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...
