Estimating Canopy Water Content of Chaparral Shrubs Using Optical Methods

Remote Sensing of Environment, 1998
Predicting fire hazard in fire-prone ecosystems in urbanized landscapes, such as the chaparral systems of California, is critical to risk assessment and mitigation. Understanding the dynamics of fire spread, topography and vegetation condition are necessary to increase the accuracy of fire risk assessment.

Retrieval of Vegetation Canopy Water Content Based on Spectral Index Method

Applied Mechanics and Materials, 2013
Based on the physical models of PROSPECT and SAIL, hyperspectral data of different scenes were simulated. According to the simulated data, we built 7 spectral indexes highly linear correlated to vegetation canopy water content, and analyzed the relationship between spectral indexes and canopy water content.

A Physically-Based Model for Canopy Water Content Retrieval

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Canopy water content (CWC) is one of the factors that influence photosynthesis and evapotranspiration. Vegetation indices have been proposed to destribe the relationship between spectral profiles and canopy water content. In this paper, we propose a retrieval method using the common swir bands of satellites (such as sentinel-2), and develop a split ...

Estimating canopy water content from spectroscopy

Israel Journal of Plant Sciences, 2012
Canopy water content is a dynamic quantity that depends on the balance between water losses from transpiration and water uptake from the soil. Absorption of short-wave radiation by water is determined by various frequencies that match overtones of fundamental bending and stretching molecular transitions.
