Relocating the 3rd Mobile Facility

June 24, 2020 2

AMF3 intended for mid-length deployments of ~5 yearsOliktok deployment began in 2013 à time to consider relocation

Workshop held in 2018 in part to identify candidates for a new location for AMF3Main options discussed:

Southeast United StatesHigh latitude regionsMaritime regionsMountainous regions/complex topographyRegions with organized deep convection

Motivation for Moving AMF3 to Southeast US

June 24, 2020 3

Opportunity to study convection in environment where local forcing is prevalentStrong coupling of convection with the surfaceSignificant sources of biogenic aerosols and scattered urban sources

The preliminary science objectives for the deployment brings these elements together

Goals for the Southeast U.S. Deployment

June 24, 2020 4

Support broad range of science themesDevelop creative strategy for addressing spatial heterogeneityDevelop collaborations with other communitiesDevelop site into an attractor for interdisciplinary researchAccomplish significant advances across science themes
