Measurement of cloud integrated backscattering coefficient with a nephelometer

Geophysical Research Letters, 1991
We describe the application of a nephelometer to in‐situ, real‐time measurement of the integrated backscattering coefficient σbs of cloud drops. For thin and moderately thick clouds, this quantity is related to the cloud albedo A, for 0° zenith solar radiation, through the relation A=σbsL, where L is the geometric cloud thickness.

Monte Carlo computations of the electron backscattering coefficient for bulk targets and surface thin films

, 2008
Monte Carlo computations of the electron backscattering coefficient as a function of the primary energy in the range 500 eV–5 keV for several bulk targets (Al, Si, Cr, Ni, Cu, Ge, Au) are provided. Monte Carlo simulated backscattering coefficients from

High‐Power Terahertz Emission from Picosecond Nano‐Plasma Switching Driven by Secondary Electron Emission Avalanche

Advanced Science, EarlyView.
A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn2+‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

Advanced Science, EarlyView.
A multifunctional benzimidazole‐terminated CNF separator is constructed via a PEI‐mediated covalent locking strategy, generating dense zincophilic sites that accelerate Zn2+ transport and desolvation while enabling uniform Zn (002) deposition and suppressing side reactions.

Parameterization of light scattering for solving the inverse problem of determining the concentrations of the principal light scattering and absorbing admixtures in shelf waters

Oceanologia, 2001
A method for estimating the water backscattering coefficient was put forward on the basis of experimental data of diffuse attenuation coefficient for downwelling irradiance and irradiance reflectance.

COSMO-SkyMed Image Investigation of Snow Features in Alpine Environment

Sensors, 2017
In this work, X band images acquired by COSMO-SkyMed (CSK) on alpine environment have been analyzed for investigating snow characteristics and their effect on backscattering variations. Preliminary results confirmed the capability of simultaneous optical

Tailoring Successive Magnetic‐Dielectric Synergy for Enhancing Electromagnetic Absorption in Ultralong Heterostructure Chains Assisted by High Static Magnetic Field

Advanced Science, EarlyView.
This work proposes a high static magnetic field (HSMF) driven dual‐low‐dimension strategy for fabricating magnetic‐dielectric heterostructure (Fe3O4@MoS2) chains with programmable lengths. The constructed successive magnetic‐dielectric synergy, arising from uniaxial anisotropy‐enhanced magnetic response and abundant heterointerfaces that boost ...

Detection of Flooded Areas Caused by Typhoon Hagibis by Applying a Learning-Based Method Using Sentinel-1 Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Typhoon Hagibis (No. 19, in Japan) made landfall in Koriyama City in Fukushima Prefecture, Japan, on October 13, 2019. The consequent floods damaged built-up areas in the city center.
