... It has not been reviewed and should not be cited or quoted, as the views expressed do not necessarily reflect the views of the Academies or the Committee on Opportunities to Improve the Representation of Clouds and Aerosols in Climate Models with National Collection Systems. Committee Members Present: Pamela Emch, Everette Joseph, Sonia Kreidenweis, Michael Prather, Jeffrey Reid, Robert Wood Committee Members Absent: Steven Ghan Academies Staff Present: Rita Gaskins, Michael Hudson, Kristina Pistone, Amanda Staudt, Katie Thomas This recap is not a comprehensive summary of all the issues discussed at the workshop.

... To inform the sponsor about specific types of data to present at the September workshop, individual workshop participants discussed a number of ways that understanding of clouds, aerosols, and their interactions could be advanced with additional data from classified assets. These concepts and issues should not be seen as conclusions of the workshop or as consensus statements of the workshop participants or organizing committee.

...  Observations from a radiative forcing perspective over the "pristine" Southern Hemisphere ocean.  Measurements of microphysical properties rather than bulk or column properties (aerosol optical depth, cloud condensation nuclei, aerosol index)

...  Polarimeter and polarized data could offer insights on droplet size distributions, for example, and in understanding the full 3D character of the atmosphere. o Retrievals of fine and coarse mode aerosol: optical depth, size distribution, complex refractive indices for each mode, cloud phase, droplet size distribution, shape, roughness, and asymmetry parameter retrievals for ice clouds, aerosols retrievals under cirrus.

... but can stay aloft for up to 6 months at approximately 18 km altitude. Such technology might be very useful over heavily instrumented surface sites such as DOE/ARM (Department of Energy's Atmospheric Radiation Measurement Program)
