RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Fog detection, Radiative Transfer Model SBDART Indo-Gangetic plain Brightness temperature difference threshold Middle Infrared Thermal Infrared
2019/2/28
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...
A MODEL TO SIMULATE THE RADIATIVE TRANSFER OF FLUORESCENCE IN A LEAF
Leaf optical properties Chlorophyll fluorescence Radiative transfer Monte-Carlo method Photon packet Ray tracing
2018/5/16
Light is reflected, transmitted and absorbed by green leaves. Chlorophyll fluorescence (ChlF) is the signal emitted by chlorophyll molecules in the leaf after the absorption of light. ChlF can be used...
GEOMETRICAL AND STRUCTURAL PARAMETERIZATION OF FOREST CANOPY RADIATIVE TRANSFER BY LIDAR MEASUREMENTS
Remote Sensing Forestry LIDAR Vegetation Modelling Structure
2015/12/30
A forest canopy is a complex system with a highly structural multi-scale architecture. Physical based radiative transfer (RT) modelling has been shown to be an effective tool for retrieval of vegetati...
MAPPING OF FOLIAR CONTENT USING RADIATIVE TRANSFER MODELING AND VIS-NIR HYPERSPECTRAL CLOSE-RANGE REMOTE-SENSING
Close-range remote sensing Hyperspectral Leaf optical properties Radiative transfer model Vegetation
2015/9/21
Most methods for retrieving foliar content from hyperspectral data are well adapted either to remote-sensing scale, for which each spectral measurement has a spatial resolution ranging from a few doze...
RADIATIVE TRANSFER MODEL INVERSION BASED ON MULTI-TEMPORAL CHRIS/PROBA DATA FOR LAI ESTIMATION
Leaf area index Radiative transfer Dynamic canopy model
2015/9/8
Leaf area index (LAI) is a key variable for the understanding and modelling of several eco-physiological processes within a
vegetation canopy. The LAI could thus provide vital information for the man...
STOCHASTIC RADIATIVE TRANSFER MODEL FOR MIXTURE OF DISCONTINUOUS VEGETATION CANOPIES
Radiative Transfer Theory Three-domensional effects
2015/9/8
Modeling of the radiation regime of a mixture of vegetation species is a fundamental problem of the Earth’s land remote sensing and
climate applications. The major existing approaches, including the ...
Radiative transfer modelling and the retrieval of biophysical variables
Radiation transfer modelling multi-angular observations bio- geophysical variable extraction
2015/9/2
Natural surfaces, such as vegetation and soil, do not - as a rule - reflect incident solar radiation equally in all directions. This
reflectance anisotropy is formally described by a Bidirectional Re...
In their Preface the authors state "…the time has come to write a textbook that acknowledges the following basic fact: The radiation that enters, or is emitted by, the ocean encounters the same basic ...
