5.6      Assimilation of GOCI AOD retrievals to improve air-quality forecasting during the KORUS-AQ period.

Ha, Soyoung, MMM/NCAR

During the Korea-United States Air Quality (KORUS-AQ) field program conducted over Korea for May-June 2016, various types of observations including the Geostationary Ocean Color Imager (GOCI) satellite were collected. Using the online coupled meteorology-aerosol analysis and forecasting system (WRF-Chem/GSI), those measurements are assimilated simultaneously in various configurations. In this talk, we compare multiple cycling experiments to examine the observation impact on the short-range air-quality forecasting, focusing on the impact of GOCI aerosol optical depth (AOD) retrievals on the prediction of fine particulate matter (PM2.5) at the surface.
