2014/12/19
Due to an oversight in the production process, the article “Implementation of a soil albedo scheme in the CABLEv1.4b land surface model and evaluation against MODIS
estimates over Australia” was publ...
Context: Hard X-rays from solar flares are an important diagnostic of particle acceleration and transport in the solar atmosphere. Any observed X-ray flux from on-disc sources is composed of direct em...
Airborne measurements from two consecutive days, analysed with the aid of an aerosol-adiabatic cloud parcel model, are used to study the effect of carbonaceous aerosol particles on the reflectivity of...
Estimated impact of black carbon deposition during pre-monsoon season from Nepal Climate Observatory – Pyramid data and snow albedo changes over Himalayan glaciers
black carbon deposition pre-monsoon season Nepal Climate Observatory Pyramid data snow albedo Himalayan glaciers
2010/8/16
The possible minimal range of reduction in snow surface albedo due to dry deposition of black carbon (BC) in the pre-monsoon period (March–May) was estimated as a lower bound together with the estimat...
Impact of brown and clear carbon on light absorption enhancement, single scatter albedo and absorption wavelength dependence of black carbon
brown and clear carbon light absorption enhancement single scatter albedo black carbon
2010/8/12
The presence of clear coatings on atmospheric black carbon (BC) particles is known to enhance the magnitude of light absorption by the BC cores. Based on calculations using core/shell Mie theory, we d...
Enhancement of marine cloud albedo via controlled sea spray injections: a global model study of the influence of emission rates, microphysics and transport
marine cloud albedo emission rates microphysics transport
2010/8/12
Modification of cloud albedo by controlled emission of sea spray particles into the atmosphere has been suggested as a possible geoengineering option to slow global warming. Previous global studies ha...
Effects of boundary layer particle formation on cloud droplet number and changes in cloud albedo from 1850 to 2000

2010/2/1
We use a global aerosol microphysics model to estimate the effect of particle formation through activation nucleation in the boundary layer (BL) on cloud droplet number concentration (CDNC) on global ...
Aerosol Single Scattering Albedo retrieval in the UV range: an application to OMI satellite validation
Aerosol Single Scattering Albedo retrieval UV range OMI satellite validation
2010/2/1
The aerosol Single Scattering Albedo (SSA) and Absorbing Aerosol Optical Depth (AAOD) at 320.1 nm are derived at Rome site by the comparison between Brewer and modelled spectra. The UVSPEC radiative t...
Not So Black? The Statistics of Albedo and Energy Recirculation on Hot Exoplanets
data analysis — (stars:) planetary systems
2010/3/8
[Abridged] We use a simple analytic model to analyze all of the published photometric observations of exoplanets. Our model has two parameters: the planets' Bond albedo, A, and its heat recirculation ...
Bounded cascade clouds:albedo and effective thickness
Bounded cascade clouds albedo effective thickness
2009/11/16
If climate models produced clouds having liquid water amounts close to those observed, they would compute a mean albedo that is often much too large, due to the treatment of clouds as plane-parallel. ...
The Influence of Uncertainty in Air Temperature and Albedo on Snowmelt
Uncertainty Air Temperature Albedo on Snowmelt
2009/10/26
Extrapolating meteorological data to the basin scale represents a major problem
of spatial snowmelt modelling in alpine terrain. Within this study errors in
air temperature introduced by regionaliza...
The progress of snow albedo for the 1991 winter from Helligdagshaugen research
site, Norway, is presented. The temporal reduction of albedo decreases
as the snow undergoes a process of metamorphosis...
CONCURRENT ANALYSIS ON DIRT AGGREGATION AND ALBEDO CHANGES ON A MELTING SNOW SURFACE
DIRT AGGREGATION MELTING SNOW SURFACE ALBEDO CHANGES
2009/10/13
Albedo of a dirty snow surface is strongly controlled by the concentration of dirt particles and their behavior (mainly aggregation phenomena) during conditions of the surface melting. The aggregation...
