Estimating canopy water content using hyperspectral remote sensing data
International Journal of Applied Earth Observation and Geoinformation, 2010 Hyperspectral remote sensing has demonstrated great potential for accurate retrieval of canopy water content (CWC). This CWC is defined by the product of the leaf equivalent water thickness (EWT) and the leaf area index (LAI). In this paper, in particular the spectral information provided by the canopy water absorption feature at 970nm for estimating ...

Retrieving vegetation canopy water content from hyperspectral thermal measurements [PDF]
Agricultural and Forest Meteorology, 2017 The retrieval of vegetation canopy water content using thermal hyperspectral (TIR, 8–14 μm) measurements is investigated in this study. Vegetation water content indicators such as fuel moisture content (FMC, %, mass-based) and equivalent water thickness (EWT, g cm−2, area based) play significant roles in plant physiology, as well as in the modelling of

A global canopy water content product from AVHRR/Metop [PDF]
ISPRS Journal of Photogrammetry and Remote Sensing, 2020 Spatially and temporally explicit canopy water content (CWC) data are important for monitoring vegetation status, and constitute essential information for studying ecosystem-climate interactions. Despite many efforts there is currently no operational CWC product available to users.

Estimating the relative water content of leaves in a cotton canopy [PDF]
Polarization Science and Remote Sensing VIII, 2017 Remotely sensing plant canopy water status remains a long term goal of remote sensing research. Established approaches to estimating canopy water status — the Crop Water Stress Index, the Water Deficit Index and the Equivalent Water Thickness — involve measurements in the thermal or reflective infrared. Here we report plant water status estimates based

Retrieving Leaf and Canopy Water Content of Winter Wheat Using Vegetation Water Indices
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018 This study investigates the capability of spectral indices for estimating winter wheat leaf and canopy water content using radiative transfer modeling and field measurements. An irrigation treatment experiment was conducted to investigate response of crop growth to water supply in 2014 and 2015.

Empirical and Physical Estimation of Canopy Water Content from CHRIS/PROBA Data [PDF]
Remote Sensing, 2013 Efficient monitoring of Canopy Water Content (CWC) is a central feature in vegetation studies. The potential of hyperspectral high spatial resolution CHRIS/PROBA satellite data for the retrieval of CWC was here investigated using empirical and physical based approaches.

Decline in stability of forest productivity in the tropics as determined by canopy water content
iScience, 2023 The impacts of low soil moisture (SM) and high vapour pressure deficit (VPD) on tree's photosynthesis and productivity are ultimately realized by changing water content in the canopy leaves. In this study, variations in canopy water content (CWC) that can be detected from microwave remotely sensed vegetation optical depth (VOD) have been proposed as a ...

New Phytologist, 2021 Summary Variation in canopy water content (CWC) that can be detected from microwave remote sensing of vegetation optical depth (VOD) has been proposed as an important measure of vegetation water stress. However, the contribution of leaf surface water (LWs), arising from dew formation and rainfall interception, to CWC is largely unknown, particularly ...

International Journal of Applied Earth Observation and Geoinformation, 2008 Canopy water content (CWC) is important for mapping and monitoring the condition of the terrestrial ecosystem. Spectral information related to the water absorption features at 970 nm and 1200 nm offers possibilities for deriving information on CWC.
