There is a clear need to study the radiative properties and climate effects of aerosols in the Eastern and Northwest Pacific regions due to the complexity of aerosol types and large emissions of aerosols. In this study, using geostationary satellite (GMS-5) data and other measurements made during the ACE-Asia Intensive Observation Period (IOP), an algorithm that dynamically incorporates aerosol properties during the satellite aerosol optical thickness (AOT) retrievals is developed. Preliminary result show that the GMS-5 retrievals from this method can capture the AOT spatial distribution with high temporal resolutions. The GMS-5 retrieved AOTs are in good agreement with the ground-based SP AOTs. This paper demonstrates the importance of the integration of ground-based and aircraft measurements into the satellite retrieval algorithms, and also shows the potential application of GMS-5 satellite to retrieve AOT in the Asian region. These high temporal resolution AOT retrievals can be further used to study the impact of aerosols on the radiation balance of the earth-atmosphere system
