The manuscript provides an opinion and perspectives on the extent to which we can use snapshots of aerosol and cloud data (e.g. from satellite measurements) to infer understanding about the processes in the system. It draws on existing work and adds some new work to demonstrate the applicability of ergodicity, space-time exchange, and the Deborah number to the problem. The manuscript is conceptual and original. It is our hope that this work will encourage the atmospheric sciences community to explore the value of these concepts more deeply.
