ACE-ASIA: Asian Pacific Regional Aerosol Characterization Experiment
The Aerosol Characterization Experiments (ACE) are designed to increase our understanding of how atmospheric aerosol particles affect the Earth's climate system. These experiments integrate in-situ measurements, satellite observations, and models to reduce the uncertainty in calculations of the climate forcing due to aerosol particles and improve the ability of models to predict the influences of aerosols on the Earth's radiation balance. ACE-Asia is the fourth in a series of experiments organized by the International Global Atmospheric Chemistry (IGAC) Program (A Core Project of the International Geosphere Biosphere Program). The Intensive Field Phase for ACE-Asia took place during the spring of 2001 (mid-March through early May) off the coast of China, Japan and Korea. The Operations Center was established at the Iwakuni Marine Corps Base, in southwestern Japan. The ACE-Asia region includes many types of aerosol particles of widely varying composition and sizes derived from one of the largest aerosol source regions on Earth. These particles include those emitted by human activities and industrial sources, as well as wind-blown dust. Results from ACE-Asia will improve our understanding of how atmospheric aerosols influence the chemical and radiative properties of the Earth's atmosphere. They will also help us understand how future changes in aerosol concentration and composition may influence changes in the Earth's climate system as a whole.
The scientific objectives of ACE-Asia are to determine and understand the properties and controlling factors of the aerosol in the anthropogenically modified atmosphere of Eastern Asia and the Northwest Pacific and to assess their relevance for radiative forcing of climate. To achieve these goals, ACE-Asia will pursue three specific objectives: 1) - Determine the physical, chemical, and radiative properties of the major aerosol types in the Eastern Asia and Northwest Pacific region and investigate the relationships among these properties. 2) - Quantify the physical and chemical processes controlling the evolution of the major aerosol types and in particular their physical, chemical, and radiative properties. 3) - Develop procedures to extrapolate aerosol properties and processes from local to regional and global scales, and assess the regional direct and indirect radiative forcing by aerosols in the Eastern Asia and Northwest Pacific region
