Estimating Underwater Light Regime under Spatially Heterogeneous Sea Ice in the Arctic

Applied Sciences, 2018
The vertical diffuse attenuation coefficient for downward plane irradiance ( K d ) is an apparent optical property commonly used in primary production models to propagate incident solar radiation in the water column. In open water, estimating K

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

Optical and biogeochemical properties of diverse Belgian inland and coastal waters [PDF]

Earth System Science Data, 2022
From 2017 to 2019, an extensive sampling campaign was conducted in Belgian inland and coastal waters, aimed at providing paired data of optical and biogeochemical properties to support research into optical monitoring of aquatic systems. The campaign was

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.

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).

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 ...
