Measurements obtained during ISDAC will be used to answer the following key questions:
- How do properties of arctic aerosols during April differ from those measured during the Mixed-Phase Arctic Cloud Experiment in October?
- To what extent do the different properties of the arctic aerosol during April produce differences in the microphysical and macrophysical properties of clouds and the surface energy balance?
- To what extent can cloud models and the cloud parameterizations used in climate models simulate the sensitivity of arctic clouds and the surface energy budget to the differences in aerosol between April and October?
- How well can long-term surface-based measurements at the ACRF NSA locale provide retrievals of aerosol, cloud, precipitation, and radiative heating in the Arctic?
