The NASA Atmosphere Observing System: Exploring Aerosol, Cloud, Convection, and Precipitation Processes

Session ID#: 158011

Session Description:
The 2017 NASA Earth Science Decadal Survey identified science and applications priorities to be addressed by several Designated Observables (DOs).  Two of these DOs, the aerosol (A) and Clouds, Convection, and Precipitation (CCP), were merged and formed the basis of the Atmosphere Observing System (AOS) that will, in conjunction with international partners, place constellations of active and passive remote sensors into two orbital planes beginning in 2028, complemented by a robust suborbital observation effort.    This session underscores the science foci of AOS that include low and high cloud feedbacks; aerosol direct and indirect radiative effects; convective properties; aerosol attribution; and applications of societal benefit derived from these observations. Abstracts are sought that address 1) how combinations of diverse observations can be used to answer AOS science questions, and 2) how present and anticipated needs of the modeling community could inform the orbital and sub orbital observational and application-oriented foci of AOS.
