A sensitivity study on the effects of particle chemistry, asphericity and size on the mass extinction efficiency of mineral dust in the earth's atmosphere: from the near to thermal IR
particle chemistry asphericity size mineral dust the earth's atmosphere thermal IR
2011/2/17
To determine a plausible range of mass extinction efficiencies (MEE) of terrestrial atmospheric dust from the near to thermal IR, sensitivity analyses are performed over an extended range of dust micr...
Sensitivity of stratospheric Bry to uncertainties in very short lived substance emissions and atmospheric transport
stratospheric Bry lived substance emissions atmospheric transport
2011/2/16
We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
Simulation of low clouds in the Southeast Pacific by the NCEP GFS: sensitivity to vertical mixing
low clouds the Southeast Pacific the NCEP GFS vertical mixing
2010/12/23
The NCEP Global Forecast System (GFS) model has an important systematic error shared by many other models: stratocumuli are missed over the subtropical eastern oceans. It is shown that this error can ...
