[ACG51-13] An Overview of NASA’s Aerosols and Clouds-Convection-Precipitation (A-CCP) Pre-formulation Study
Keywords:aerosol, clouds, convection, precipitation, satellite
A critical element of the A-CCP observing strategy is to make extensive use of new passive and active sensors as well as of the so-called Program-of-Record (PoR), complemented by a fully integrated sub-orbital component. Central to this observing system design is the adoption of a Value Framework in which quantitative assessment of the science benefits of space- and air-borne assets is a key element. Given pre-defined A-CCP science objectives and geophysical variables with desired accuracies, A-CCP relies on a spectrum of Observing System Simulation Experiments (OSSEs) aimed at addressing pixel level retrieval uncertainties and sampling trade-offs.
In this talk we present an overview of the ACCP study. Starting with its roots at the 2017 Decadal Survey, we will outline the main goals and science objectives of ACCP, followed by a brief description of the study approach, value framework and architectures being considered. We will then highlight OSSEs activities being conducted, namely, synergistic retrievals involving passive/active sensors of particular relevance for the A-CCP science objectives and the key architectures being considered.
