DUSTIEAIM-EDNA

Coarse-Mode eDNA during DUSTIEAIM

10 October 2026 - 20 April 2027

Lead Scientist: Sonia Kreidenweis

Observatory: AMF (ARM Mobile Facility 1)

The Desert-Urban System Integrated Atmospheric Monsoon (DUSTIEAIM) campaign is planned to collect data starting June 1, 2026. The first ARM Mobile Facility (AMF1) will operate for 18 months at the Main Site, located within the Phoenix metropolitan area on the Arizona State University-West Campus. DUSTIEAIM’s science focus is to quantify the bimodal water cycle during the winter and summer, and energy budgets at the urban/rural/agricultural interface of the southwestern U.S. as regional air masses and meteorological patterns change throughout the year in response to the seasonal cycle. This campaign adds to this focus by characterizing the coarse-mode composition in the spring and fall. The approach is to provide size-resolved aerosol sampling that captures diurnal cycles of aerosol, with sufficient collection volumes to enable unique characterization methods including sequencing of biological material.
