The Atlantic Tradewind OceanAtmosphere 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 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. These data include aircraft instrument microphysics data in netcdf file and video quick-looks showing size distributions and scalar summaries along with aircraft position in mp4 format.

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.

Current components, physical, ocean circulation, wind circulation, and other data were collected from moored buoys, CTD casts, drifting buoys, and in situ wind recorders from AIRCRAFT and other platforms from the North Atlantic Ocean and other locations. Data were collected by the Woods Hole Oceanographic Institution (WHOI) and other institutions as part of the Seasonal Response of the Equatorial Atlantic Experiment/Français Océan et Climat dans l'Atlantique Equatorial (SEQUAL/FOCAL) project from 25 January 1980 to 18 December 1985. Data has been processed by NODC to the standard NODC F015-Current Meter Data (Components), F022-CTD High Resolutions, F101-Wind Measurements from Buoys, and F156-Ocean Drifter Data formats. This F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments. The F101 file format is used for time-series measurements of wind and other surface meteorological parameters taken at fixed locations. The instrument arrays may be deployed on automated buoys, ships, or towers. Position, platform type and height, and instrument elevation are reported for each station. The data record comprises values of east-west (u) and north-south (v) wind components at specified date and time. Wind values may be subject to averaging or filtering and are typically reported at time intervals of 10-15 minutes. Air temperature, atmospheric pressure, and dewpoint temperature may also be reported. The F156 file format is used for time series data on ocean circulation determined by the tracking of drifting buoys, drogues, or other instrumented devices as they are carried with the flow. Movement is reported as point-to-point geographic locations determined by shore-based, surface ship, aircraft, or satellite observations. Data from both ocean currents and ice movement can be reported in this format over time periods ranging from minutes to months. Directions and speeds between individual observations may be computed from these data and presented in graphic or summary listing form to provide information on circulation patterns and mass transport in offshore and near- shore regions. Platform name (for platform acquiring data or deploying device), drogue characteristics, start and

This dataset includes surface underway, chemical, meteorological and physical data collected from M/S New Century 2 in the North Pacific Ocean, Caribbean Sea, North Atlantic Ocean from 2016-01-03 to 2016-11-03.
