5. What makes AQAST unique? All AQAST projects connect Earth Science and air quality management  Involve active partnerships with air quality managers, have deliverable application outcomes  Expand relationships through meetings, online tools, newsletters, surveys AQAST has flexibility in how it allocates its resources  Members adjust work plans to meet evolving air quality needs  Multi-member “Tiger Teams” are organized each year in consultation with air quality management community to address pressing problems requiring coordinated activity  AQAST is self-organizing and can respond quickly to demands Quick, collaborative, flexible, responsive to the needs of the AQ community www.aqast.org 5
