Cirrus clouds cover approximately 20–25% of the globe and thus play an important role in the Earth's radiation budget. Therefore the effect of aerosols on cirrus clouds can have a substantial impact o...
In addition to microphysical changes in clouds, changes in nucleation processes of ice cloud due to aerosols would result in substantial changes in cloud top temperature as mildly supercooled clouds a...
The shortwave radiative forcing bias of liquid and ice clouds from MODIS observations
shortwave radiative forcing liquid and ice clouds MODIS observations
2009/8/25
We present an assessment of the plane-parallel bias of the shortwave cloud radiative forcing (SWCRF) of liquid and ice clouds at 1 deg scales using global MODIS (Terra and Aqua) cloud optical property...
Oxidation of SO2 by H2O2 on ice surfaces at 228 K: a sink for SO2 in ice clouds
SO H2O2 ice surfaces SO2 ice clouds
2009/3/12
The heterogeneous reaction SO2 + H2O2 H2SO4 on ice at 228 K has been studied in a low temperature coated-wall flow tube. With H2O2 in excess of SO2, the loss of SO2 on an ice surface is time depende...
Ice condensation on sulfuric acid tetrahydrate: Implications for polar stratospheric ice clouds
Ice condensation sulfuric acid tetrahydrate polar stratospheric ice clouds
2009/3/11
The mechanism of ice nucleation to form Type 2 PSCs is important for controlling the ice particle size and hence the possible dehydration in the polar winter stratosphere. This paper probes heterogene...
Probing ice clouds by broadband mid-infrared extinction spectroscopy: case studies from ice nucleation experiments in the AIDA aerosol and cloud chamber
Probing ice clouds broadband mid-infrared extinction spectroscopy ice nucleation experiments AIDA aerosol cloud chamber
2009/1/16
Series of infrared extinction spectra of ice crystals were recorded in the 6000–800 cm−1 wavenumber regime during expansion cooling experiments in the large aerosol and cloud chamber AIDA of For...
Extinction coefficients retrieved in deep tropical ice clouds from lidar observations using a CALIPSO-like algorithm compared to in-situ measurements from the cloud integrating nephelometer during CRYSTAL-FACE
