ATOMIC ship Doppler lidar: Continuous profiles of vertical velocity and uncalibrated aerosol backscatter intensity at a wavelength of 1.5 micron in the atmospheric boundary layer measured by a vertically-stabilized Doppler Lidar aboard NOAA Ship Ronald H. Brown in the North Atlantic Ocean, near Barbados: Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign 2020-01-07 to 2020-02-12 (NCEI Accession 0225372)

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 measurements from a NOAA WP-3D Orion "Hurricane Hunter" aircraft, NOAA Ship Ronald H. Brown, and unpiloted vehicles launched from Barbados and from NOAA Ship Ronald H. Brown. This dataset consists of Doppler lidar data in netCDF files.
