Clouds close to the surface of the ocean, called shallow convective clouds, are found around the world – but poorly represented in weather and climate models.
Shallow convection, the effects of clouds on the ocean surface energy budget, and oceanic processes are relevant to a myriad NOAA applications such as climate sensitivity, propagation of the Madden-Julian Oscillations (MJO), hurricane track and intensity, annual movement of the Intertropical Convergence Zone, midlatitude storm tracks, and marine stratocumulus cloud regions. Shallow convection is also an important issue for weather forecast models over land, with implications for convective inhibition and the initiation of thunderstorms or for solar energy forecasting. The oceanic region of interest is the middle of the Atlantic Warm Pool.
For ATOMIC, NOAA brings their unique observing platforms to complement the European field campaign, EUREC4A. NOAA’s science objectives will emphasize energy exchange between the ocean and atmosphere, and cloud–aerosol interactions. It is expected that this work will be done by NOAA in collaboration with the National Science Foundation.
The campaign has been endorsed by the World Climate Research Programme's CLIVAR project.

NOAA and CIRES researchers from the Physical Sciences Laboratory will collect measurements using the Air-Sea Flux System and additional oceanographic instruments aboard the NOAA Ship Ronald H. Brown. In partnership with the University of Washington, PSL will collect similar observations of near-surface atmospheric conditions, air-sea energy exchanges, waves, and the upper ocean from six drifting SWIFT drifting buoys and two Wave Gliders. On the NOAA P-3 aircraft, measurements will be taken by the W-Band cloud radar, stepped frequency microwave radiometer for wind, wide swath radar altimeter for waves, and tail Doppler X-band precipitation radar. In parnership with the University of Colorado (CIRES and IRISS), PSL's newly-developed miniFlux instrument package will fly on a small, island-based RAAVEN drone. PSL will also provide forecast guidance for planning and conduct post-experiment data and model analysis.
