Heterogeneous freezing of droplets with immersed mineral dust particles – measurements and parameterization
droplets immersed mineral dust particles measurements parameterization
2010/8/12
During the measurement campaign FROST (FReezing Of duST), LACIS (Leipzig Aerosol Cloud Interaction Simulator) was used to investigate the immersion freezing behavior of size selected, coated and uncoa...
Parameterizing the competition between homogeneous and heterogeneous freezing in ice cloud formation – polydisperse ice nuclei
heterogeneous freezing ice cloud formation polydisperse ice nuclei
2009/8/25
This study presents a comprehensive ice cloud formation parameterization that computes the ice crystal number, size distribution, and maximum supersaturation from precursor aerosol and ice nuclei. The...

heterogeneous freezing desert dust samples
2009/5/6
We present results of experiments at the aerosol interactions and dynamics in the atmosphere (AIDA) chamber facility looking at the freezing of water by three different types of mineral particles at t...
Parameterizing the competition between homogeneous and heterogeneous freezing in cirrus cloud formation – monodisperse ice nuclei
homogeneous and heterogeneous freezing cirrus cloud formation monodisperse ice nuclei
2009/3/12
We present a parameterization of cirrus cloud formation that computes the ice crystal number and size distribution under the presence of homogeneous and heterogeneous freezing. The parameterization is...
Heterogeneous freezing of single sulfuric acid solution droplets: laboratory experiments utilizing an acoustic levitator
Heterogeneous freezing single sulfuric acid solution droplets laboratory experiments acoustic levitator
2009/3/6
The heterogeneous freezing temperatures of single binary sulfuric acid solution droplets were measured in dependency of acid concentration down to temperatures as low as -50°C. In order to avoid influ...
