ICE-T project description

Ice in Clouds Experiment - Tropical

Summary

The objective of the Ice in Clouds - Tropical (ICE-T) experiment is to show that under given conditions, direct ice nucleation measurement(s), or other specific measurable characteristics of the aerosol, can be used to predict the number of ice particles forming by nucleation mechanisms in selected clouds. The PIs also seek improved quantitative understanding of the roles of thermodynamic pathway, location within the cloud, and temporal dependency. The ICE-T study will draw on lessons learned in ICE-L (2007), but will extend the investigations to towering warm cumulus clouds, where both primary and secondary ice formation processes occur. The project, which is lead by Andy Heymsfield (NCAR), will be based in St Croix, US Virgin Islands. The NSF/NCAR C-130 will support the project during May 2011. In-situ instrumentation will measure the chemical, physical, and cloud activating properties of aerosols, and will include both offline and real-time methods of analysis, including A-ATOFMS.
