Breakout Summary Report

Join us for an engaging and informative session on critical updates and discussions regarding how the DOE AAF and TBS support ARM/ASR missions. This session aims to bring together researchers, scientists, and stakeholders to discuss ongoing activities and strategic improvements to enhance atmospheric data collection and analysis. The primary goal of this session is to facilitate a collaborative dialogue with ARM Facility users. We will showcase technological advancements and recent AAF and TBS improvements while gathering user input to identify future needs and development areas. By gathering diverse insights, we hope to foster collaboration and develop partnerships to leverage the enhanced capabilities and broaden future scientific inquiries.

Main Discussion Points:

• mSEMS could be used in a mode where only one size is measured but at a much higher data rate compared to scanning. Could aid in the identification of new particle formation (NPF) events.

• Integration of WIBS data with EMSL biological particle identification. This will happen at the BNF site with the FICUS proposal.

• Expansion of EMSL chemical analysis to include size distributions.

• TBS deployment at NSA: working progress for approval

• Deployment of guest instruments on ArcticShark. Need ARM to standardize the process.

• ArcticShark turbulence flights and TBS operations at NSA.

• Air pollution measurement in the western US using ArcticShark and TBS, with a focus on central California.

• Consideration of surface measurements for synergy with ArcticShark and TBS airborne measurements.

• Exploration of restricted areas to allow for in-cloud measurements

• Potential for additional UAS operations alongside AMFs.

• Importance of TKE data and accessibility.

• Adjustments to operating strategies of UAS and TBS instruments.

• Engineering support is required for instrumentation changes.

• Technical requirements and constraints for guest instruments on ArcticShark.

• AIMMS data motion correction and the need for technical documentation.

• Overlapping ArcticShark and TBS at BNF is planned, with more substantial overlaps in June and August 2025.

• TBS night flights have been planned for BNF and SGP

• Engineering modifications require formal requests (ENG put-in process).

• ArcticShark and TBS deployments offer significant potential for understanding vertical dynamics and pollution formation. The joint flights of TBS/Arctic Shark were also encouraged during other sessions.

• Cloud operations in restricted airspace present an opportunity for additional atmospheric studies. This also came up in other sessions regarding being able to fly in cloud for both TBS and ArcticShark and where that could potentially occur

• mSEMS and EMSL enhancements could improve particle identification capabilities.

• Potential insights can be derived from the PMF analysis of UAS chemical composition data using the MN-AMS technique developed by Qi Zhang’s group. MB-AMS should become one of the baseline measurements.

• ARM needs to engage the community in siting planning earlier.

• ArcticShark deployments are currently tied to ARM sites, but flexibility should exist for other locations based on user interest. The ENA and NSA sites have been mentioned several times in the polling results.

• TBS TKE data is under evaluation. UAS TKE data is a mentor-edited dataset and has been released for the May 2024 campaign.

• ARM has no or limited VOC measurements. Need those capabilities, especially at the BNF site.

N/A

• Collaboration with other agencies (such as, California Air Resources Board) for air quality studies in the southern region.

• Cloud operation of TBS/UAS within restricted areas.

• Identification of restricted areas aligning with cloud science goals.

• Additional ArcticShark UAS units that can be operated alongside AMFs.

• Flexibility to modify operation parameters and payload configurations.

• More site options (ENA and NSA) for airborne (UAS/TBS) deployments.

• Clear guidelines for guest instrument integration (5-10 lbs, shoebox size, ENG process).

• Adding VOC measurements to TBS and ArcticShark
