Mapping Chaparral in the Santa Monica Mountains Using Multiple Endmember Spectral Mixture Models
- D. Roberts, M. E. Gardner, R. Church, S. Ustin, G. Scheer, R. Green
- Geology
- 1 September 1998
Abstract A new technique, called multiple endmember spectral mixture analysis (MESMA), was developed and tested in the Santa Monica Mountains, using Airborne Visible/Infrared Imaging Spectrometer… Expand
PROSPECT-4 and 5: Advances in the leaf optical properties model separating photosynthetic pigments
- J. Féret, C. Francois, +6 authors S. Jacquemoud
- Geology
- 16 June 2008
Abstract The PROSPECT leaf optical model has, to date, combined the effects of photosynthetic pigments, but a finer discrimination among the key pigments is important for physiological and ecological… Expand
Estimating leaf biochemistry using the PROSPECT leaf optical properties model
- S. Jacquemoud, S. Ustin, J. Verdebout, G. Schmuck, G. Andreoli, B. Hosgood
- Geology
- 1 June 1996
Abstract The biophysical, biochemical, and optical properties of 63 fresh leaves and 58 dry leaves were measured to investigate the potential of remote sensing to estimate the leaf biochemistry from… Expand
Vegetation in deserts. I - A regional measure of abundance from multispectral images. II - Environmental influences on regional abundance
- M. Smith, S. Ustin, J. Adams, A. Gillespie
- Geography, Geology
- 1990
Abstract A method was tested in the semiarid Owens Valley, California for measuring sparse vegetation cover using Landsat Thematic Mapper (TM) multispectral images. Although green vegetation has a… Expand
Remote sensing of nitrogen and lignin in Mediterranean vegetation from AVIRIS data: Decomposing biochemical from structural signals
- L. Serrano, J. Peñuelas, S. Ustin
- Geology
- 1 August 2002
Remote sensing estimates of vegetation nitrogen (N) and lignin concentration are central to assess ecosystem processes such as growth and decomposition. Although remote sensing techniques have been… Expand
Water content estimation in vegetation with MODIS reflectance data and model inversion methods
- P. Zarco-Tejada, Carlos A. Rueda, S. Ustin
- Geology
- 25 April 2003
Statistical and radiative-transfer physically based studies have previously demonstrated the relationship between leaf water content and leaf-level reflectance in the near-infrared spectral region.… Expand
Remote sensing of plant functional types.
Conceptually, plant functional types represent a classification scheme between species and broad vegetation types. Historically, these were based on physiological, structural and/or phenological… Expand
An introduction to the NASA Hyperspectral InfraRed Imager (HyspIRI) mission and preparatory activities
- C. Lee, M. Cable, +4 authors E. Middleton
- Geology
- 15 September 2015
Abstract In 2007, the NASA Hyperspectral InfraRed Imager (HyspIRI) mission was recommended in Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond (Decadal… Expand
Winter rainfall interception by two mature open‐grown trees in Davis, California
- Q. Xiao, E. McPherson, S. Ustin, M. Grismer, J. Simpson
- Geology
- 1 March 2000
A rainfall interception measuring system was developed and tested for open-grown trees. The system includes direct measurements of gross precipitation, throughfall and stemflow, as well as continuous… Expand
Mapping nonnative plants using hyperspectral imagery
- E. Underwood, S. Ustin, D. DiPietro
- Geology
- 30 July 2003
Nonnative plant species are causing enormous ecological and environmental impacts from local to global scale. Remote sensing images have had mixed success in providing spatial information on land… Expand
