Characterisation of the artificial neural network CiPS for cirrus cloud remote sensing with MSG/SEVIRI [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
Cirrus clouds remain one of the key uncertainties in atmospheric research. To better understand the properties and physical processes of cirrus clouds, accurate large-scale observations from satellites are required.

Validation of SCIAMACHY top-of-atmosphere reflectance for aerosol remote sensing using MERIS L1 data [PDF]

open access: yesAtmospheric Chemistry and Physics, 2007
Aerosol remote sensing is very much dependent on the accurate knowledge of the top-of-atmosphere (TOA) reflectance measured by a particular instrument.

Retrieval of aerosol optical thickness over snow and ice surfaces in the Arctic using Advanced Along Track Scanning Radiometer [PDF]

open access: yes, 2011
Aerosols in the Arctic cause radiative forcing and a variety of climatic feedbacks, which affect climate of both local and global scales. In order to assess the state of the Arctic climate, information on the aerosol type and amount is needed.

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Optical micromanipulation of aerosols [PDF]

open access: yes, 2009
This thesis describes my work on the development of optical trapping techniques for manipulating airborne particles. Although many of the basic principles are similar to those used in more conventional colloidal experiments, there are many differences

Column aerosol optical properties based on the sky-radiometer measurement at Ny-Alesund in the Arctic spring of 2006 and 2007

open access: yesAntarctic Record, 2010
Sky-radiometer measurements have been performed in Ny-Alesund with Prede POM-01 since March 2000, and followed by POM-02 since May 2004. Aerosol optical properties, i.e., optical thickness, single scattering albedo and refractive index for selected ...

Atmospheric controls on mineral dust emission from the Bodélé Depression, Chad: The role of the low level jet [PDF]

open access: yes, 2005
Atmospheric aerosols play an important though uncertain role in the Earth's climate system. The Bodélé Depression in Chad stands out as the planet's largest source of dust, yet very little is known about the atmospheric circulation that maintain this ...
