Observation and Modeling of Regional Aerosol Radiative Effects

Project Details


Current assessment of aerosol radiative effect is hindered by our incomplete knowledge of aerosoloptical properties, especially absorption. The scientific objective of this project belongs to the7-SEAS project configuration. The goal of the 7-SEAS project is attempting to understand theenvironmental and radiative impacts due to biomass-burning and Chinese haze aerosols. In thisstudy, we will analysis data from 2010-2016 7-SEAS field campaigns to quantify the opticalproperties of aerosols in source, transport, and sink regions. The physicochemical evolution ofaerosols during the long-range transport will be discussed. Finally, we will apply the researchoutcomes to carry out a better estimation on aerosol radiative effects. The surface in situ,ground-base, and satellite remote sensing measurements will be integrated and applied to quantifythe aerosol optical properties over the study region. We will also collaborate with the NASASMARTLabs, AERONET, and MPLNET to obtain the aerosol data in the region. Finally, amethod, combining observed data and radiative transfer simulations, will be proposed to betterquantify the aerosol radiative effect. To complete the above proposed research configuration, thelidar calibration and UAV facility will be a critical need. The instrument budget requirement isproposed in this project. By investing the facility, it will not only support this project but alsoadvance our technology in the field. For the integration project and other sub-projects, the resultsfrom this project can be used to directly compare with other measured air pollutants. Our resultwill also facilitate the detailed design of numerical experiments, the validation of themodel/satellite results, and satellite retrieval algorithms development. Overall, the proposedproject armed with a complete set of radiation and aerosol optical properties measurements,propose a method towards integrating observations and radiative transfer models to preciselyquantify the aerosol radiative effects and their uncertainties.
