Evaluating the potential of multi-view data extraction from small Unmanned Aerial Systems (UASs) for object-based classification for Wetland land covers

GIScience & Remote Sensing, 2019
Unmanned Aerial Systems (UASs) have the potential to provide multi-view data, but the approaches used to extract the multi-view data from UAS and investigation of their use in image classification are currently unavailable in publications to our best ...

A Method of Retrieving BRDF from Surface-Reflected Radiance Using Decoupling of Atmospheric Radiative Transfer and Surface Reflection

Remote Sensing, 2018
Bi-directional reflection distribution function (BRDF) defines anisotropy of the surface reflection. It is required to specify the boundary condition for radiative transfer (RT) modeling used in aerosol retrievals, cloud retrievals, atmospheric modeling,

High Accuracy Solar Diffuser BRDF Measurement for On-Board Calibration in the Solar Reflective Band

Remote Sensing, 2023
In the solar reflective band, an on-board calibration method based on a solar diffuser (SD) can realize full aperture, full field of view, and end-to-end absolute radiometric calibration of optical remote sensors.

Estimating the Impact of Impounding an 85‐km2 Hydropower Reservoir in a Subarctic Environment on the Local Radiation Balance

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract This study focuses on the net radiative forcing caused by the impoundment of an 85‐km2 hydroelectric reservoir in the subarctic Côte‐Nord, Quebec, Canada (50.69°N, 63.24°W, mean depth of 44 m). Using spectral bands from the Landsat 7 ETM+ and Landsat 8 OLI/TIRS satellites, we observed spatial and temporal variations in albedo and surface ...

Development of a New BRDF-Resistant Vegetation Index for Improving the Estimation of Leaf Area Index

Remote Sensing, 2016
The leaf area index (LAI) is one of the most important Earth surface parameters used in the modeling of ecosystems and their interaction with climate. Numerous vegetation indices have been developed to estimate the LAI. However, because of the effects of

Estimating Physically-Based Reflectance Parameters From a Single Image With GAN-Guided CNN

IEEE Access, 2022
We present a method that estimates the physically accurate reflectance of materials from a single image and reproduces real world materials which can be used in well-known graphics engines and tools.

All‐Sky Assimilation of FY‐4B AGRI Reflectance in the CMA‐MESO Model With ARMS as a Forward Operator

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract All‐sky assimilation of visible and near‐infrared observations has attracted widespread attention. In the CMA‐MESO model, this study proposes an optimized reflectance scheme based on the Ross‐Li bidirectional reflectance distribution function (BRDF) model.

A Universal BRDF Archetype Database for Normalizing Directional Reflectance to Nadir BRDF Adjusted Reflectance

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Surface reflectance varies with changes in solar and viewing angles, exhibiting distinct anisotropic reflectance characteristics, which can be characterized using the bidirectional reflectance distribution function (BRDF).

Two-parameter boundary condition applied to transverse acoustic impedance of a Fermi liquid

, 2017
We discuss surface scattering in terms of bidirectional reflectance distribution function. We formulate a boundary condition that in addition to diffuse and specular reflection has tilted diffuse reflection.

Highly Resolved Surface Phytoplankton Community Composition Along the British Columbia Coast, Derived From In Situ Hyperspectral Radiometry

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Quantitative measurements of phytoplankton community composition (PCC) are essential for understanding fisheries production, ocean nutrient cycling, and the export of particulate carbon to the ocean interior. However, these measurements are constrained in dynamic coastal waters due to the spatial‐temporal constraints of in situ sampling ...
