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
2011/2/25
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...
Solar irradiance at the earth's surface: long-term behavior observed at the South Pole
the earth's surface long-term behavior the South Pole
2011/2/25
This research examines a 17-year database of UV-A (320–400 nm) and visible (400–600 nm) solar irradiance obtained by a scanning spectroradiometer located at the South Pole. The goal is to define the v...
Aerosol nucleation and its role for clouds and Earth's radiative forcing in the aerosol-climate model ECHAM5-HAM
Aerosol nucleation clouds and Earth's radiative forcing the aerosol-climate model ECHAM5-HAM
2010/11/30
Nucleation from the gas phase is an important source of aerosol particles in the Earth's atmosphere, contributing to the number of cloud condensation nuclei, which form cloud droplets. We have impleme...

Reply to: “Tropical cirrus and water vapor: an effective Earth infrared iris feedback?”
Tropical cirrus water vapor effective Earth infrared iris feedback
2009/3/12
In assessing the iris effect suggested by Lindzen et al. (2001), Fu et al. (2002) found that the response of high-level clouds to the sea surface temperature had an effect of reducing the climate sens...
Tropical cirrus and water vapor: an effective Earth infrared iris feedback?
Tropical cirrus water vapor effective Earth infrared iris feedback
2009/3/11
We revisit a model of feedback processes proposed by Lindzen et al. (2001), in which an assumed 22% reduction in the area of tropical high clouds per degree increase in sea surface temperature produce...
