The frequency of drought periods influences the yield potential of crops under field
conditions. The change in morphology and anatomy of plants has been tested during …

This paper reviews the different remote sensing techniques found in the literature to monitor
plant water status, allowing farmers to control the irrigation management and to avoid …

The normalized difference vegetation index (NDVI) has been widely used for remote
sensing of vegetation for many years. This index uses radiances or reflectances from a red …

We present new remote sensing indices of plant water status: the ratio between the
reflectance at 970 nm, one of the water absorption bands, and the reflectance at a reference …

This paper outlines the first part of a series of research studies to investigate the potential
and approaches for using optical remote sensing to assess vegetation water content. It first …

Scientists with the Agricultural Research Service (ARS) and various government agencies
and private institutions have provided a great deal of fundamental information relating …

Natural disturbances induced by insect outbreaks have increased in forest ecosystems over
the past decades. To minimize economic loss and prevent a mass outbreak, early detection …

Leaves of six species selected to represent a broad range in internal structure were
collected in the field and studied in the laboratory to determine primary and secondary …

Two different configurations of a shortwave infrared water stress index (SIWSI) are derived
from the MODIS near-and shortwave infrared data. A large absorption by leaf water occurs in …

Spectral reflectance in the visible and near-infrared wavelengths provides a rapid and
inexpensive means for determining the mineralogy of samples and obtaining information on …
