Sb doping influence on structural properties of ZnO thin films

Materials Research Express, 2020
Pure and Sb doped ZnO thin films were homogeneously prepared at room temperature on the soda-lime glass substrates (SLG) via the spin coating technique. The effects of the Sb ratio on structural properties, morphological properties and optical properties

Underwater optical environment in the coastal waters of British Columbia, Canada

FACETS, 2017
We describe the underwater light field of the Strait of Georgia in spring and summer, using apparent optical properties (reflectance, attenuation coefficient of downwelling irradiance, the average cosine of downwelling irradiance, and the attenuation of ...

Remote Sensing of Spatiotemporal Variation of Apparent Optical Properties in Bohai Sea

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
It has been presented in this study, the evaluation of remote sensing reflectance ( ${\bm R}_{\bm rs}$ ) derived from the atmospheric correction of Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Aqua satellite. A switching algorithm was developed for the atmospheric correction. The evaluation shows that MODIS measured ${\bm R}_{\bm rs}

Concentration, anisotropic and apparent colour effects on optical reflectance properties of virgin and ocean-harvested plastics

Journal of Hazardous Materials, 2021
We present reflectance measurements collected from virgin and ocean-harvested plastics. Virgin plastics included high and low density polyethylene (HDPE, LDPE), polypropylene (PP) as well as polystyrene (PS). Ocean-harvested plastics were ropes, sheets, foam, pellets and fragmented items previously trawled from the North Pacific Garbage Patch.

Estimating specific inherent optical properties of tropical coastal waters using bio-optical model inversion and in situ measurements: case of the Berau estuary, East Kalimantan, Indonesia

, 2010
Specific inherent optical properties (SIOP) of the Berau coastal waters were derived from in situ measurements and inversion of an ocean color model. Field measurements of water-leaving reflectance, total suspended matter (TSM), and chlorophyll a (Chl a)

Tuning magnetic, electronic, and optical properties of Mn-doped NiCr2O4 via microwave method

Journal of Saudi Chemical Society, 2021
The main aim of the paper to the synthesis of Mn (x)-doped NiCr2O4 nanoparticles by varying Mn content (x = 0.00%, 0.01%, 0.02%, and 0.03%) by microwave method for correlating the effect of NiCr2O4 on structural, optical, and magnetic properties of the ...

Assessment of Remote Sensing Reflectance Glint Correction Methods from Fixed Automated Above-Water Hyperspectral Radiometric Measurement in Highly Turbid Coastal Waters

Remote Sensing
Fixed automated (unmanned) above-water radiometric measurements are subject to unavoidable sky conditions and surface perturbations, leading to significant uncertainties in retrieved water surface remote sensing reflectances (Rrs(λ), sr−1).

Remote sensing reflectance reconstruction to obtain water optical properties from MERIS multispectral satellite images

, 2010
We use a multiple regression analysis and a data bank of about 400 reflectance spectra to reconstruct hyperspectral reflectances between 400 and 900 nm with a 5 nm step using only the values known at the wavelengths of the MERIS sensor level 2 data.

How small is a small cloud? [PDF]

Atmospheric Chemistry and Physics, 2008
The interplay between clouds and aerosols and their contribution to the radiation budget is one of the largest uncertainties of climate change. Most work to date has separated cloudy and cloud-free areas in order to evaluate the individual radiative ...
