The Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) and the Coastal Urban Plume Dynamics Study (CUPiDS) field campaigns were led by the National Oceanic and Atmospheric Administration's Chemical Sciences Laboratory (NOAA CSL) and occurred from June – August 2023. The AEROMMA campaign investigated the anthropogenic and marine emissions that alter tropospheric composition and impact air quality and climate over North America and focused on understanding the changing paradigms in emissions and the future of urban air quality, refining our understanding of the marine atmosphere, and validating remote sensing capabilities from satellites in urban and remote atmospheres. AEROMMA deployed around 30 state-of-the-art instruments, which comprehensively measured meteorological parameters, trace gases, and aerosols on NASA's DC-8 aircraft. In coordination with AEROMMA, the CUPiDS campaign deployed 5 instruments on the NOAA Twin Otter and deployed 2 NOAA ground-based lidars to the Yale Coastal Field Station in Connecticut. CUPiDs focused on measuring dynamics and chemistry over the New York City region. This data repository is a snapshot of the final data as of 10 February 2025.

This dataset contains physical, optical, and chemical properties of atmospheric marine aerosols from four different cruises aboard WHO R/V Atlantis as part of the NAAMES project. The dates of the four cruises are as follows: NAAMES-1 - 06 November to 29 November 2015 NAAMES-2 - 11 May to 03 June 2016 NAAMES-3 - 30 August to 23 September 2017 NAAMES-4 - 20 March to 12 April 2018 The data from each cruise is divided into multiple csv datasets, summarized as follows: Main - Navigation, Meteorology, Scattering, and Absorption; Chemistry - Aerosol species concentrations at varying particle diameters; Radon - Radon Concentration; CCN - Cloud Condensation Nuclei; Size Distribution (APS) - Aerodynamic Particle Size Distribution; Size Distribution (DMPS) - Differential Mobility Particle Size Distribution; Size Distribution - Merged version of the APS and DMPS datasets

This dataset provides results of selected in-situ measurements of airflow and aerosol particles collected during the following airborne campaigns: NASA Atmospheric Tomography (ATom), Saharan Aerosol Long-range Transport and Aerosol-Cloud-interaction Experiment (SALTRACE), and Absorbing aerosol layers in a changing climate: aging, lifetime and dynamics (A-LIFE). The airborne campaigns were conducted between 2013-06-10 and 2018-05-21. Depending upon the aircraft instrumentation per flight and campaign, the data include aircraft position, relative humidity, temperature, pressure, angle of attack (AOA), the probe location, true and probe air speeds, and aerosol particle diameters as extracted from Cloud Imaging Probe (CIP) images for the ATom and A-LIFE flights. Also provided are the results of combining the airborne data with numerical modeling to simulate particle sampling efficiency. Simulations investigated how airflow around wing-mounted instruments affected sampling efficiency and the induced errors for different realistic flight conditions.

The Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC) was a field campaign held January-February 2020 in the tropical North Atlantic east of Barbados. The campaign, the U.S. complement to the European field campaign called EUREC4A, was aimed at better understanding cloud and air-sea interaction processes. ATOMIC included in measurements from a NOAA WP-3D Orion "Hurricane Hunter" aircraft, the research ship Ronald H. Brown, and unpiloted vehicles launched from Barbados and from the Ronald H. Brown.
