Abstract EN
Mineral dust and ice cloud observations from the Infrared Atmospheric Sounding Interferometer (IASI) are used to assess the relationships between desert dust aerosols and ice clouds over the tropical Atlantic Ocean during the hurricane season 2008.
Cloud property histograms are first adjusted for varying cloud top temperature or ice water path distributions with a Bayesian approach to account for meteorological constraints on the cloud variables.
Then, histogram differences between dust load classes are used to describe the impact of dust load on cloud property statistics.
The analysis of the histogram differences shows that ice crystal sizes are reduced with increasing aerosol load and ice cloud optical depth and ice water path are increased.
The distributions of all three variables broaden and get less skewed in dusty environments.
For ice crystal size the significant bimodality is reduced and the order of peaks is reversed.
Moreover, it is shown that not only are distributions of ice cloud variables simply shifted linearly but also variance, skewness, and complexity of the cloud variable distributions are significantly affected.
This implies that the whole cloud variable distributions have to be considered for indirect aerosol effects in any application for climate modelling.
