The general aerosol-related scientific questions the AOS is designed to address are related to assessing the magnitude of aerosol DIRECT and INDIRECT radiative effects, as they relate to Earth's energy budget. While the direct effect relates to how aerosols directly (on their own) interact with solar and terrestrial radiation via scattering and absorption, the indirect effect generally describes how aerosols act to modify earth's radiative budget due to their influence on clouds. Due to its complexity, the aerosol indirect effect, in particular, is poorly understood from a scientific standpoint, and represents a large source of uncertainty for predictions of future climate.
AOS Inlet Stack
Because the AOS is a system of instruments that are all generally housed within the same enclosure, each component AOS instrument may or may not be susceptible to problems either affecting the entire AOS enclosure or other component AOS instruments plumbed upstream/downstream of the instrument of interest. In these ways, the AOS poses unique challenges to the DQ Office's data quality monitoring initiatives.
There is currently an AOS at SGP E13, NSA X1, ENA C1 and 3 mobile AOS platforms, each with an AMF. The component instruments comprising the AOS include:

Currently, there are no known issues affecting entire AOS systems. These would be any that are not worth noting in AOS-related DQAs. Please add any here as you see fit.
Currently, there are no past problems affecting entire AOS systems. These would be any that are worth noting in AOS-related DQAs. Please add any here as you see fit.
