Retrieval of Leaf Area Index (LAI) and Soil Water Content (WC) Using Hyperspectral Remote Sensing under Controlled Glass House Conditions for Spring Barley and Sugar Beet [PDF]

, 2010
Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or ...

Bottom Reflectance in Ocean Color Satellite Remote Sensing for Coral Reef Environments

Remote Sensing, 2015
Most ocean color algorithms are designed for optically deep waters, where the seafloor has little or no effect on remote sensing reflectance. This can lead to inaccurate retrievals of inherent optical properties (IOPs) in optically shallow water ...

Initial Performance Analysis of the At-Altitude Radiance Ratio Method for Reflectance Conversion of Hyperspectral Remote Sensing Data

Sensors, 2022
In remote sensing, the conversion of at-sensor radiance to surface reflectance for each pixel in a scene is an essential component of many analysis tasks.

The influence of coherent waves on the remotely sensed reflectance

Optics Express, 2001
Oceanic waves have been found to contribute enhanced back-scattering in the direction of the illumination source in studies that assumed the ocean surface to be a random sum of waves. Here we investigate enhanced back-scattering by coherent capillary-gravity wave trains that co-exist near the crests of short gravity waves in the ocean. We find that the

RADIO-WAVES REFLECTION AT REMOTE SENSING OF UNDERLYING COVERS

Civil Aviation High TECHNOLOGIES, 2019
Monitoring technologies are rapidly developing at present and allow to extract and use non-coordinate information about objects. Noncoordinate information is the information about the type and properties of an object under study. Remote sensing is the main method of solving monitoring problems where special positioning belongs to the radar methods ...

C/NOFS remote sensing of ionospheric reflectance [PDF]

Journal of Geophysical Research: Space Physics, 2016
AbstractAlfvén waves play critical roles in the electrodynamic coupling of plasmas at magnetically conjugate regions in near‐Earth space. Associated electric (E*) and magnetic (δB*) field perturbations sampled by sensors on satellites in low‐Earth orbits are generally superpositions of incident and reflected waves.

The sedimentary and remote‐sensing reflection of biomass burning in Europe

Global Ecology and Biogeography, 2017
AbstractAimWe provide the first European‐scale geospatial training set relating the charcoal signal in surface lake sediments to fire parameters (number, intensity and area) recorded by satellite moderate resolution imaging spectroradiometer (MODIS) sensors.

Improved Aerosol Optical Thickness, Columnar Water Vapor, and Surface Reflectance Retrieval from Combined CASI and SASI Airborne Hyperspectral Sensors

Remote Sensing, 2017
An increasingly common requirement in remote sensing is the integration of hyperspectral data collected simultaneously from different sensors (and fore-optics) operating across different wavelength ranges.

Fine scale optical remote sensing experiment of mixed stand over complex terrain (FOREST) in the Genhe Reserve Area: objective, observation and a case study

International Journal of Digital Earth, 2021
Optical remote sensing allows to efficiently monitor forest ecosystems at regional and global scales. However, most of the widely used optical forward models and backward estimation methods are only suitable for forest canopies in flat areas. To evaluate
