Sen2Cor Atmospheric Correction with Meteorological Aerosol Optical Thickness [PDF]

, 2018
Sen2Cor is a Level-2A processor with the main purpose to correct single-date Sentinel-2 Level1C products from the effects of the atmosphere in order to deliver a Level-2A surface reflectance(SR)product. Side products are Cloud Screening and Scene Classification, Aerosol Optical Thickness (AOT) and Water Vapour(WV) maps.

Fast and simple model for atmospheric radiative transfer [PDF]

, 2010
Radiative transfer models (RTMs) are of utmost importance for quantitative remote sensing, especially for compensating atmospheric perturbation. A persistent trade-off exists between approaches that prefer accuracy at the cost of computational complexity,

Ångström coefficient as an indicator of the atmospheric aerosol type for a well-mixed atmospheric boundary layer: Part 1: Model development

Oceanologia, 2009
The physical and optical properties of an atmospheric aerosol mixture depend on a number of factors. The relative humidity influences the size of hydroscopic particles and the effective radius of an aerosol mixture.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

PbS colloidal quantum dots imagers: From single devices to arrays, flexible platforms, and CMOS‐integrated systems

FlexMat, EarlyView.
Abstract Imagers operating in the visible to near‐infrared (NIR) range play an important role in applications such as industrial sorting, security surveillance, and autonomous driving. However, conventional imaging technologies based on silicon and III–V semiconductors suffer from several limits, including restricted spectral range, high fabrication ...

Aerosol direct radiative effect at the top of the atmosphere over cloud free ocean derived from four years of MODIS data [PDF]

Atmospheric Chemistry and Physics, 2006
A four year record of MODIS spaceborne data provides a new measurement tool to assess the aerosol direct radiative effect at the top of the atmosphere. MODIS derives the aerosol optical thickness and microphysical properties from the scattered sunlight ...
