Atlantic Tradewind Ocean–Atmosphere Mesoscale Interaction Campaign
The Atlantic Tradewind Ocean–Atmosphere Mesoscale Interaction Campaign (ATOMIC) is a field study to investigate atmospheric shallow convection and air-sea interaction in the tropical North Atlantic east of Barbados. During January–February 2020, this NOAA-led effort will deploy instruments from a research ship and aircraft to measure key cloud and air-sea interaction processes that are needed to improve understanding and prediction of the impacts of shallow convection on weather and climate conditions on the U.S.
In an effort to advance understanding of these processes, the ESRL Physical Sciences Division will join with other NOAA Research laboratories, the NOAA Climate Program Office’s Climate Variability and Predictability Program, and several universities during the winter of 2020 to lead ATOMIC.
This U.S. field campaign will collaborate with an intensive European study, called EUREC4A (ElUcidating the Role of Clouds-Circulation Coupling in ClimAte), to investigate atmospheric shallow convection and air-sea interaction in the tropical North Atlantic east of Barbados. NOAA will deploy instruments from a research ship and aircraft to measure key cloud and air-sea interaction processes. This effort will involve a unique combination of manned and unmanned aircraft and ships including newly developed capabilities using UAVs, saildrones, and underwater gliders to characterize the variaibility of oceanic and atmospheric properties.
