Mediterranean cloud system variability inferred from satellite observations
Mediterranean cloud system satellite observations
2010/1/27
The variability of Mediterranean cloud systems is investigated using 8.5 years (from January 1987 to June 1995) of TIROS-N Operational Vertical Sounder (TOVS) observations acquired aboard the National...
Exploitation of cloud top characterization from three-channel IR measurements in a physical PMW rain retrieval algorithm
three-channel IR measurements physical PMW
2010/1/27
Rainfall intensity estimates by passive microwave (PMW) measurements from space perform generally better over the sea surface with respect to land, due to the problems in separating true rain signatur...
The effect of Arctic sea-ice extent on the absorbed（net）solar flux at the surface, based on ISCCP-D2 cloud data for 1983–2007
Arctic sea-ice absorbed solar flux ISCCP-D2 cloud data
2010/2/1
We estimate the effect of the Arctic sea ice on the absorbed (net) solar flux using a radiative transfer model. Ice and cloud input data to the model come from satellite observations, processed by the...

2009/12/31
The relationship between the multi-spectral cloud field characterization from the Advanced Very High Resolution Radiometer (AVHRR) and the rainfall intensities from the Advanced Microwave Sounding Uni...
On the relationship of polar mesospheric cloud ice water content, particle radius and mesospheric temperature and its use in multi-dimensional models
polar mesospheric cloud ice water content mesospheric temperature multi-dimensional models
2009/12/3
The distribution of ice layers in the polar summer mesosphere (called polar mesospheric clouds or PMCs) is sensitive to background atmospheric conditions and therefore affected by global-scale dynamic...
UV Raman lidar measurements of relative humidity for the characterization of cirrus cloud microphysical properties
UV Raman lidar measurements relative humidity cirrus cloud microphysical properties
2009/12/3
Raman lidar measurements performed in Potenza by the Raman lidar system BASIL in the presence of cirrus clouds are discussed. Measurements were performed on 6 September 2004 in the frame of the Italia...
Retrieval of atmospheric profiles and cloud properties from IASI spectra using super-channels
atmospheric profiles cloud properties IASI spectra super-channels
2009/12/3
The Infrared Atmospheric Sounding Interferometer (IASI) is an ultra-spectral satellite sensor with 8461 spectral channels. IASI spectra contain high information content on atmospheric, cloud, and surf...

Cloud sensitivity studies for stratospheric and lower mesospheric ozone profile retrievals from measurements of limb-scattered solar radiation
Cloud sensitivity stratospheric and lower mesospheric ozone profile limb-scattered solar radiation
2010/2/8
Clouds in the atmosphere play an important role in reflection, absorption and transmission of solar radiation and thus affect trace gas retrievals. The main goal of this paper is to examine the sensit...
