dc.description.abstractWith their extensive coverage, marine low clouds greatly impact global climate. Presently, marine low clouds are poorly represented in global climate models, and the response of marine low clouds to changes in atmospheric greenhouse gases and aerosols remains the major source of uncertainty in climate simulations. The Eastern North Atlantic (ENA) is a region of persistent but diverse subtropical marine boundary layer clouds, whose albedo and precipitation are highly susceptible to perturbations in aerosol properties. In addition, the ENA is periodically impacted by continental aerosols, making it an excellent location to study the cloud condensation nuclei (CCN) budget in a remote marine region periodically perturbed by anthropogenic emissions, and to investigate the impacts of long-range transport of aerosols on remote marine clouds. The Aerosol and Cloud Experiments in Eastern North Atlantic (ACE-ENA) campaign was motivated by the need of comprehensive in-situ measurements for improving the understanding of marine boundary layer CCN budget, cloud and drizzle microphysics, and the impact of aerosol on marine low cloud and precipitation. The airborne deployments took place from June 21 to July 20, 2017 and January 15 to February 18, 2018 in the Azores. The flights were designed to maximize the synergy between in-situ airborne measurements and ongoing long-term observations at a ground site. Here we present measurements, observation strategy, meteorological conditions during the campaign, and preliminary findings. Finally, we discuss future analyses and modeling studies that improve the understanding and representation of marine boundary layer aerosols, clouds, precipitation, and the interactions among them.en_US
dc.description.sponsorshipThe ACE-ENA campaign would not have been successful without the contributions of many individuals including the G-1 flight, ground, and instrument support crew (M. Hubbell, C. Eveland, J. Ray, J. Hubbe, M. Crocker, P. Carroll, F. Reis, A. Mendoza, D. Nelson, M. Newburn, and W. Irvin), the ENA site staff (P. Ortega, C. Sousa, B. Cunha, and T. Silva), Field Instrument and Operation (FIDO) staff at Los Alamos National Laboratory (K. Nitschke, and H. Powers), and other participating scientists (Nitin Bharadwaj, Bradley Isom, Jennifer Kafka, and Stephen Springston). We acknowledge the support from the Government of the Autonomous Region of the Azores, the Minister of Science of Portugal, and the Air Force of Portugal through the Command of the Air Space of the Azores, command and all the air force staff of Airbase Nº 4 (Lajes). The ACE-ENA field campaign was supported by the Atmospheric Radiation Measurement (ARM) Climate Research Facility and the Environmental Molecular Sciences Laboratory (EMSL), both are U.S. Department of Energy (DOE) Office of Science User Facilities sponsored by the Office of Biological and Environmental Research. We thank Dr. Tamara Pinterich for her help in the preparation and deployment of the FIMS onboard the G-1 aircraft during ACE-ENA. The research was supported by the Atmospheric System Research (ASR) program as part of the DOE Office of Biological and Environmental Research under award Nos. DE-SC0020259 (J. Wang), DE-SC0012704 (BNL), DE–SC0016522 (D. Mechem), DE-SC0021167 (C. Chiu), DE-SC0018948 (A. Laskin and R. Moffet), DESC0016370 (D. Knopf), KP1701000/57131 (J. Shilling and M. Zawadowicz), DE-AC02-06CH11357 (V. Ghate), and DE-SC0020053 (R. Shaw). S. S. Yum and J. Yeom acknowledge the support of Korea Meteorological Administration Research and Development Program under Grant KMI2018-03511. Chunsong Lu and Sinan Gao were supported by the National Natural Science Foundation of China (41822504). Xiquan Dong was supported by the NSF project under grant AGS-2031751 and as part of the “Enabling Aerosolcloud interactions at GLobal convection-permitting scalES (EAGLES)” project (74358), funded by the U.S. Department of Energy, Office of Biological and Environmental Research, Earth System Modeling program with a subcontract to the University of Arizona.
