Estimation of phytoplankton concentration from downwelling irradiance measurements in water

, 2012
The downwelling irradiance spectrum is so far not used directly for the determination of water constituents, mainly due to the large and unpredictable fluctuations of the underwater light field induced by the water surface.

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

Advanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Utilizing Downwelling Irradiance for Phytoplankton Determination

, 2012
The downwelling irradiance is rarely utilized to determine optical parameters of a water body since the ever-changing water surface induces strong signal fluctuations in the upper meters of typically 20 to 40 %.

Electrode‐Engineered Dual‐Mode Multifunctional Lead‐Free Perovskite Optoelectronic Memristors for Neuromorphic Computing

Advanced Electronic Materials, EarlyView.
A lead‐free perovskite memristive solar cell structure that call emulate both synaptic and neuronal functions controlled by light and electric fields depending on top electrode type. ABSTRACT Memristive devices based on halide perovskites hold strong promise to provide energy‐efficient systems for the Internet of Things (IoT); however, lead (Pb ...

Solar irradiance reconstruction over the telescopic era using a revised photospheric magnetic field model

Astronomy & Astrophysics
The Sun is the primary source of energy for Earth and one of the main external drivers of its climate. Solar irradiance – the radiative power emitted by the Sun and received at 1 AU – varies on all observable timescales. It is measured as the total solar

SOLAR SPECTRAL IRRADIANCE, SOLAR ACTIVITY, AND THE NEAR-ULTRA-VIOLET

The Astrophysical Journal, 2015
The previous calculations of the Solar Spectral Irradiance (SSI) by the Solar Radiation Physical Modeling, version 2 system, are updated in this work by including new molecular photodissociation cross-sections of important species, and many more levels and lines in its treatment of non-LTE radiative transfer.

A model-based approach to correcting spectral irradiance data using an upward-looking airborne sensor (CASI ILS)

, 2001
A number of aircraft sensors have the facility to measure spectral downwelling irradiance using a sensor mounted on the roof of the aircraft, but these data are rarely used for atmospheric correction.
