A simple parameterization of the short-wave aerosol optical properties for surface direct and diffuse irradiances assessment in a numerical weather model
he short-wave aerosol optical properties surface direct
2014/12/18
Broadband short-wave (SW) surface direct and
diffuse irradiances are not typically within the set of output
variables produced by numerical weather prediction (NWP)
models. However, they are freque...

Stress dependent rock physics models are being used more routinely to link mechanical deformation and stress perturbations to changes in seismic velocities and seismic anisotropy. In this paper, we in...
Spatial Variability of Selected Soil Properties in Relation to Different Land Uses in Northern Kgalagadi (Matsheng), Botswana
Kgalagadi Soils Land-Use Types Variation of Soil Properties
2013/3/11
Spatial variability of selected soil attributes were investigated in the Kgalagadi region. Soil samples were collected along transects at Hukuntsi, Tshane, Lokgwabe and Lehututu at 50 m, 200 m, 500 m,...
Banded Iron Formations (BIFs) and Associated Sediments Do Not Reflect the Physical and Chemical Properties of Early Precambrian Seas
Early Precambrian BIF Non-Marine Polar Regions
2013/3/7
Ring-in-ring structures in Australian Early Precambrian banded iron formation (BIF) were identified as bubbling mud wavelets, which lithified during temporary exposure, contradicting the alleged BIF d...
Geotechnical Properties of Problematic Soils Emphasis on Collapsible Cases
Soil Collapse South Rudasht Dorcheh Sivand

The great Indian haze revisited: aerosol distribution effects on microphysical and optical properties of warm clouds over peninsular India
The great Indian haze aerosol distribution effects microphysical optical properties of warm clouds
2010/9/10
The Indian subcontinent is undergoing a phase of rapid urbanisation. Inevitable fallout of this process is a concomitant increase in air pollution much of which can be attributed to the infamous grea...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...
