A42A:
Advances in Atmospheric Aerosol and Cloud Characterization II


Session ID#: 10905

Session Description:
Innovative instruments – such as multi-beam cross-track dual wavelength lidars and multiangle, multi-wavelength polarimeters – and improved algorithms have been advocated in recent years to reduce uncertainties in aerosol-cloud interactions and climate forcing studies. Knowledge of aerosol and cloud properties is also needed for atmospheric correction to ensure precise land and ocean surface characterization. Several advanced remote sensing instruments were developed and deployed in recent field campaigns, including PODEX, SEAC4RS, SABOR, and CalWater 2015, and improved atmospheric correction is a critical part of NASA’s-planned PACE mission. The goal of this session is to assemble expertise in radiative transfer theory, state-of-the-art instrumentation, and data applications to showcase recent advances in the study of aerosol and cloud properties, and atmospheric correction approaches. Papers on new sensor concepts, microphysical and optical modeling, remote sensing theory, observations and data analysis from airborne and spaceborne instruments are invited with a focus on aerosol and clouds.
